Total Posts: 8 | Is there any way for BASIC to know if there is a character on a given point (i.e. 3,4) and if so, how to make a variable change if it gets rid of it? I'm looking for something like the following:
:If Output(P,Q,"+")
:R-1->R
I know that isn't correct syntax, but I think it's illustrative enough of what I want to have happen. If interested, you can see my game, a WIP, Here

If P=A and Q=B:Then: Do whatever
A and B being the vars that store the values you need to trigger, and just makes sure both work at the same time to trigger it. If this is not what you need, please be more specific?

Total Posts: 8 | OK, here's what I'm doing. I am making a game where you put plus signs on the screen while avoiding an asterisk. I didn't store the information where each plus mark has been put because there can be too many of them on the screen at once. And to make an plus sign appear, you simply use the d-pad and one appears automatically. The things I need to do are this:
#1 - If there is already a plus sign where the cursor has moved, do not add 1 to R (R being the score)
#2 - If the asterisk moves to a place where there is a plus sign, subtract 1 to R (The asterisk already deletes the + sign.) |
