Making a platformer, how to stop sprite from going through walls.

szym73

I am making a platformer, and I just can't work out how to stop my sprites from going through walls. I managed to make a working floor and gravity, but that doesn't stop the sprite going through walls.

ask [please help] and wait

when green flag clicked
forever
if <([y position v] of [ground sprite v]) > ([y position v] of [player sprite v])> then
set y to (([y position v] of [ground sprite v]) + (1))
end
end

I don't think that would work, as the sprite would be trying to walk on the ground sprite, but wouldn't manage to because it would keep getting pushed back because it is standing on the thing that pushes it back. You get it?

ok, so i looked at this, and good idea, but thing is, if i wanted to use this then i would have to use all of the tutorial for this to work. I just want something to be compatible with my platformer. I shared this on an alt account for you guys to look at and determine what would be the best way to do this.

ok, so heres how you stop it from going through walls, set the walls to 1 colour and do the following:

when green flag clicked
forever 
if < touching color [#FFFFF] ?> then
 set x to (oldx)
 set y to (oldy)

end

Don't forget to describe the variables to move it back when you make it.

What if the walls are the same colour as the ground? Meh. I'll try it anyway.
