Can som1 help me with this i hav added the char.to walk and jump but when he jumps you can keep on pressing the spacebar to jump which is annoyin becoz i only want him to jump once at a time can any1 fix this and perhaps explain how uu done it,
also when i walk over a particular surface i fall??? dont know why??
One more thing i want to add friction to my walking i hav tried but not succeded by adding an actor, using the keydown event typing in xvelocity = 5; and on the draw actor xvelocity = xvelocity + 1 but the animation jsut goes off to the right can u explain and hep on this topic too plz??
plz help and explain.. =)

You need a variable, that is 1 while you are colliding, and when you stop colliding, it is 0. In the jump, use an if statement, like this:

Code: Select all

if(collidevariable == 1)
{
    code for jumping goes here...
}


This way you will jump only when you're colliding with the platform...
I'm not sure wether I understand your problem, but I think you mean, that your actor doesn't stop. So, in the Key up, of the actor, you must say xvelocity = 0; So that it stops. But I don't know what you mean by adding friction...
Anyway, I hope this helped!
