How To Make An Object Fly Once I Trigger It?

[gosseyn]

i have problems making this to run well, this is what i do(i try to make a chair fly a bit in the air when player collide with a script area) :

i create the function that will make the chair fly :

Code: (Select All)

void ChairFly()
{
AddPropImpulse("MyChair", 0.0f, 15.0f, 0.0f, "world");
}

and then inside OnStart i add this :

Code: (Select All)

AddEntityCollideCallback("player", "AreaChairFly", "ChairFly", true, 1);

What is wrong? Thanks!
