Problem with variables and force of gravity (a crash)

First of all, I have a variable called g and 2 istances of the same sprite.

When a player collides with an instance, it is deleted and if g=0 then g=1 and if g=1 then g=0.

But construct reads events top-down, so g stays at 0.

I tried using the tricks (1-Global('g')) but that didn't work because I found a crash :

make 2 events like this :

When g = 0 set force of gravity to 20

When g = 1 set force of gravity to -20

Try to run the layout, it crashes Construct...

Is there any work-around this bug? I need it badly for my game.

Can you upload the .cap that crashes to the tracker? That way we can fix the crash instead of trying to avoid it...

The crash might be a bug that needs fixing, but your (1-Global('g') is wrong.

+Player collides with sprite
   -Set g to (0 minus g)
   -Set force of gravity to g
[/code:1c9dxf6b]

This will toggle back and forth between 20 and -20.

This will toggle back and forth between 20 and -20.

sorry, won't this toggle between 0 and -1? Also I can't post the cap right now, because im not at the main pc

Nope. And sorry, I forgot to say "make the initial value for g either 20 or -20."

So if g is 20 then 0-g (zero minus twenty) will be -20.

And if g is -20 then 0-g (zero minus minus twenty) will be 20.

Just try it. It will work
