Is there a key or a manipulation that makes the text disappear?
Because it is very often superimposed on the animations.
I find that a bit of a shame.
as far as i know, no, there is not. I've seen how to modify the transparency of the text box and also the size, color and transparency of the letters. but individually, for an event, as example. to do it automatically along all the game, when desired, just pushing a key on the keyboard.. no, that characteristic, as far as i know, was not included in rpg maker xp (which is a very old program), and i wouldn't know how to create it by myself within the code. I'm not a programmer myself.
I've been able to modify part of the code and to learn a bit, basically because of the need to do so, but i wouldn't be able to write a code from zero able to modify at this level the characteristics provided by the editor itself.
So.. If you know how to do it.. , then i would be glad to include it in the game. Feel free to do a search on internet about this issue. Maybe You could find something. Maybe someone figure it out time ago and, in this case, you could tell me about it (and i would try to put it on the game on your name), or you could try to put it yourself (using github).
I mean... your idea is good. But, right now, i wouldn't know how to do that.
