Ren'Py Renpy sandbox help

[SweetGames]

Hello I am working for a while on a renpy sandbox. and have some system problems. Looking for someone who can help me fix the problems. please Private Message.

thank you

Generally you want to post the part of the code that is troubling you and the issues you are having. There is a separate part of the forum if you are looking for a dev to make your project.

To what GNVE said, I want to add that it's a public forum for a good reason.

Whatever the issue one have, it's really unlikely that it is and will stay the only one to have it. Therefore a public answer help everyone and contribute to the community.


Edit: By the way, sorry GNVE, had a power outage some times ago while answering your post regarding AI bots. It lasted the whole night, and I just remember now that I never answered, without having a fucking clue regarding where the thread can be

ok, so my problem is that i have a time system that i want to connect to the navigation.

on the map are 11 imagebuttons, each of them should represent a destination. The each of these 11 imagabuttons opens a window with info about the travel location and its 3 buttons foot, bus, car.

so you click on foot, bus or car and jump to the desired travel label.

i get that but if i jump for example from home to park the new starting point is not home but park.
from there the travel times to each location are different than from home.


example: player travels from home to park + 40min
player is in park goes back to map + 0min
player goes back to park + 0

and there is my problem, here he counts again 40+ by foot or 20 by bus or 10 by car. But he is still in the park. Only when other travels there. would be counted again at the park +.


home > by foot to the park 40min
> by bus to the park 20min
> by car to park 10min

home > to home 0 min

home > walk to fitness 50min
> by bus to fitness 25min
> by car to fitness 15min

home > walk to store 40min
> by bus to the store 20min
> by car to the store 10min

store > walk to park 20min
> by bus to the park 10min
> by car to park 5min

park > walk to fitness 10min
> by bus to fitness 5min
> by car to fitness 2min

etc. From each location it should have different travel times.

have already tried it on several ways but can't get it to work.

thanks

Hmm...

Not necessarily the optimal approach, but a dict is one way to solve this:

/!\ Warning, wrote in the fly. There's possible typos /!\

#  Travel time from /key/ to all the destination.
#  The tuple being ordered: walk, bus, car.
define travelTime = { "park": { "home": ( 20, 10, 5 ), "store": ( 15, 7, 3 ), "park": None },
                                 "home": { "home": None, "store": ( 10, 5, 2 ), "park": (20, 10, 5 ) },
                                 [...] }

# Where the player currently is.
default currentLocation = "home"

screen travelUI():

    imagebutton:
        auto "home_%s.png"
        # While be not sensitive (so not clickable) if there's no travel value, from the
        # current location to "home" ; what mean that it's where we are.
        sensitive not travelTime[currentLocation]["home"] is None
        # A screen to select how to move, passing it the expected destination.
        action Show( "moveScreen", "home" )

    imagebutton:
        auto "park_%s.png"
        sensitive not travelTime[currentLocation]["park"] is None
        action Show( "moveScreen", "park" )

    [...]

screen moveScreen( where ):

    vbox:
        textbutton "walk":
            # Add the travel time by feet from the current location to the destination.
            # Hide the current screen.
            # Jump to an entry label for the destination.
            action [ SetVariable( "currentTime", currentTime + travelTime[currentLocation][where][0] ), Hide(), Jump( where + "Hub" ) ]

        textbutton "bus":
            action [ SetVariable( "currentTime", currentTime + travelTime[currentLocation][where][1] ), Hide(), Jump( where + "Hub" ) ]

        textbutton "car":
            action [ SetVariable( "currentTime", currentTime + travelTime[currentLocation][where][2] ), Hide(), Jump( where + "Hub" ) ]


# The entry label for the park
label parkHub:
    # Update the current location, then do whatever you want.
    $ currentLocation = "park"
    [...]

label homeHub:
    $ currentLocation = "home"
    [...]

[...]

Side note: It should be possible to limit the "travelUI" screen to four lines:

screen travelUI():

    for location in [ "home", "park", "store" ]:
        imagebutton:
            auto "{}_%.png".format( location)
            action Show( moveScreen, location )

Edit: Typos in the code ; added the forgot warning.

 

[GNVE]

For code I'm not the best so You probably want to follow AON. One optimization I could see is:

define travelTime = { "park": { "home": 20, "store": 15, "park": None },
                                 "home": { "home": None, "store": 10, "park": 20},
                                 [...] }

with the bus and car buttons just dividing the base time in 2 and 4 respectively (or whatever you want). Especially with a lot of locations and/or more transport options it might be a little easier to keep the overview. But that might be just personal preference.

action [ SetVariable( currentTime, currentTime + travelTime[currentLocation][where] ), Hide(), Jump( where + "Hub" ) ]

        textbutton "bus":
            action [ SetVariable( currentTime, currentTime + round(travelTime[currentLocation][where] / 2) ), Hide(), Jump( where + "Hub" ) ]

        textbutton "car":
            action [ SetVariable( currentTime, currentTime + round(travelTime[currentLocation][where] / 4 ) ), Hide(), Jump( where + "Hub" ) ]

*please note I have not tested if this actually works in Ren'Py. Might be a little more complicated than I imagine it to be. That is why I generally leave the coding to people like AON who know what they are doing...

Something I want you to consider from a players perspective is that I generally dislike travel times in games. Especially when I don't get clear guidance where the next peace of content is. In some games I literally spend half the day just traveling to various locations to find a nugget of content.
So If you want to add travel time I would strongly suggest also baking in a way to see on the travel screen where the next piece of content is (and whether it is new or if it is a repeatable event.)

with the bus and car buttons just dividing the base time in 2 and 4 respectively (or whatever you want).

It's what I wanted to do at first, but I noticed that travel like home to fitness and park to fitness do not match the 2 and 4 followed by the other travels.
This said, I followed his approach to not be too confusing, but I agree with you that it would be better.

action [ SetVariable( currentTime, currentTime + round(travelTime[currentLocation][where] / 2) ), Hide(), Jump( where + "Hub" ) ]

*please note I have not tested if this actually works in Ren'Py.

It works, but personally I would have used int( travelTime[currentLocation][where] / 2 ).
round() will round the value, therefore 1.51 will become 2. This will int() will get rid of the decimal, so 1.99 will still become 1.
But it's a question of personal taste. I come from a time where float values where rarely used, and so I expect 3 / 2 to be equal to 1

I'm tempted to add that personally it's strict time in games that I tend to dislike.

I have nothing against periods (morning, noon, etc.), nor even with generic times (1AM, 2AM, etc) since they are just a 24 periods approach. But strict time, therefore something where minutes also count, it quickly become annoying.
Either it need that you plan your whole day, because you want to catch that even that happen between 14:32 and 14:45. This with the risk to miss it because in between you'll trigger an event that will mess with your planing ; what mean that quickly you do only one event a day, just passing time until you can catch it.
Or it's totally useless, because the event will happen at any time between 14:00 and 14:59. Therefore there's no need for the minutes, and you wonder why you've to be bothered by them.

This doesn't mean that "walking", "taking the bus", "using a car", is a bad idea, but it shouldn't be a question of time.
By example, in Killer Project it permit to have different random scenes, depending on your choice. This while in Super Powered walking will cost you energy, asking for someone to drive you will cost you favors (but can lead to sex), and if I remember correctly taking the bus cost you money. But with both games it will just get you to your destination without having a different impact on the time.
For Super Powered, there's also a notion of distance, there's place that are expected to be too far, and therefore that you can't walk to.

 

[GNVE]

Don't do this! Doing this is silly but also a little fun (If I where to do a sandbox it might end in the game just because...).

But you could place all buildings on a grid (using excel if need be) and have different modes of travel be advantageous for different distances. (doing it in pseudo code because lazy ).
so something like:
home: 1,1
store: 2,1
park: 3,2
church: 4,7
school: 6,7
work: 19,19

now subtract x1 from x2 and y1 from y2
eg store to work 2 - 20 =-17 and 1-20=-18
making sure to invert those two values if negative like in this case
add the values for total distance = 35

now calculate travel time per mode of transport (time to start + (Distance / KMPH *60)
walking: 0 + (35 / 5 * 60) =420
Cycling 5 + (35 / 12 * 60) =300
Car 30 + (35 / 23 * 60) =121
PT 45 + (35 / 25 * 60) =129

but for home to the store it would look like
walking: 0 + (1 / 5 * 60) =12
Cycling 5 + (1 / 12 * 60) =10
Car 30 + (1 / 23 * 60) =32
PT 45 + (1 / 25 * 60) =47

(For the figures I quickly googled speeds for city traffic. the base time is the time it takes to get to your car or bike and park it at the destination. For the bus it assumes having to walk to the stop and having to wait a while.)

do not understand what I am doing wrong
[/CODE]

 

[anne O'nymous]

now subtract x1 from x2 and y1 from y2
eg store to work 2 - 20 =-17 and 1-20=-18
making sure to invert those two values if negative like in this case
add the values for total distance = 35

Your formula isn't wrong, but it apply to wargame maps with square cells. You pass in all vertical and horizontal cells, and therefore have to count them all.

But in the present case, it's not the formula that should be used, but the one everyone use as example to say that Math teach you nothing useful. Yeah, for once in your life you had to use Pythagoras theorem

Therefore, the distance between those two locations is square root of ( (x2 - x1)² + (y2 - y1)² ), so 24.75.
For Ren'Py it would be:

init python:

    import math

    def distance( x1, x2, y1, y2 ):
        a = x2 - x1
        b = y2 - y1
        return math.srqt( a*a + b*b )

Hmm, it's not you, it's me. Or, more precisely, it's me, then you.

I was already thinking about the rest, and messed the syntax for Show(). Then you misunderstood the reason why you got a "NameError" error.

It should be Show( "moveScreen", "home" ), sorry.

 

[SweetGames]

I have also tried but the same.

Don't do this! Doing this is silly but also a little fun (If I where to do a sandbox it might end in the game just because...).

But you could place all buildings on a grid (using excel if need be) and have different modes of travel be advantageous for different distances. (doing it in pseudo code because lazy ).
so something like:
home: 1,1
store: 2,1
park: 3,2
church: 4,7
school: 6,7
work: 19,19

now subtract x1 from x2 and y1 from y2
eg store to work 2 - 20 =-17 and 1-20=-18
making sure to invert those two values if negative like in this case
add the values for total distance = 35

now calculate travel time per mode of transport (time to start + (Distance / KMPH *60)
walking: 0 + (35 / 5 * 60) =420
Cycling 5 + (35 / 12 * 60) =300
Car 30 + (35 / 23 * 60) =121
PT 45 + (35 / 25 * 60) =129

but for home to the store it would look like
walking: 0 + (1 / 5 * 60) =12
Cycling 5 + (1 / 12 * 60) =10
Car 30 + (1 / 23 * 60) =32
PT 45 + (1 / 25 * 60) =47

(For the figures I quickly googled speeds for city traffic. the base time is the time it takes to get to your car or bike and park it at the destination. For the bus it assumes having to walk to the stop and having to wait a while.)

don't need to complicate things as much but a version of this is how he should do it instead of having that huge travelTime blob of locations and travel times.

SweetGames you already place the locations on the map with xalign and yalign. so place those values in variables and use the values to calculate the distance to travel. that way, everything will be calculated automatically when you place a location on the map. you never have to worry about it.

i disagree with anne on the math unless you use "fly like a bird" travel. this is travelling in a city and that generally means the streets are laid out in grids. you don't go in a straight line from point A to point B. that would fit better for travel cross country.

With action ShowMenu( "moveScreen", "park" )I get this error

I'm sorry, but an uncaught exception occurred.

[GNVE]

you haven't yet defined the currentTime variable or made a typo in the name somewhere. (based on the error)

In this case this is the important bit of the error message :
NameError: name 'currentTime' is not defined

 

[SweetGames]

no only in this file is currentTime

 

[GNVE]

just like traveltime you need to set currentTime near the beginning:

define currentTime = 0

You said that you "have already tried it on several ways but can't get it to work", but haven't provided information regarding the base code, therefore I used explicit, but generic, variable names that you are supposed to adapt to your current code.
Since you want a travel system, you surely already have an equivalent to the currentLocation variable. Yet I explicitly declared it because it is the core component of the system ; you need to works with the location before the move, and it's not necessarily implicit in the code.
But for currentTime, I haven't gone this far, expecting the name to be really explicit enough for you to replace it by whatever name you gave to the variable you use to keep track of the current time. Something that you already do, because you surely haven't decided to use a precise time value for the travel before you even implement the time system in the core mechanism of your game.

AttributeError: 'int' object has no attribute 'rpartition'

On me again... And, like for Show(), it's something that you should have been able to fix yourself by just reading the doc for SetVariable() ; doc that is on your computer, in the "doc" folder that come with Ren'Py SDK.

Should be SetVariable( "currentTime", currentTime + travelTime[currentLocation][where][0] ), with "currentTime" being replace by the name of the variable used to keep track of the current time value in the time system you already use.


*sigh*
For once I forgot to warn that I wrote the code on the fly, it had to be this time...

 

[SweetGames]

thx for all.
