I am trying to fling a player using Physics Launch, but it does nothing. I'm not sure that I understand the parameters of Physics Launch fully. Here is the code:

player PhysicsLaunch( player.origin, 20 );

Thanks in advance!

PhysicsLaunch( contact_point, initial_force );

you need to specify the force as a vector though, so like:  ( x,y,z ) but this only works for script_models i think. Try using launch() or setvelocity().
Prob the last one will give the best result.

I'm still a bit unsure what a vector is. Let's say I set the vector to (50, 30, 10), will the launched object/person go to that point on the coordinate grid, or will they move 50 on the x axis, 30 on the y axis, and 10 on the z axis. Pretty much, is it a specific position or a distance relative from the player/object?

vector's arent my strongest point either. it's the direction of the force applied ( ? i think ), it's def not the coordinate's. Look in the scripting reference for some functions you can use related to vector's, or ask someome who understands them, lol.

You might want to take into consideration the fact that you can't play the phsyicslaunch function on a player as it doesn't seem to do anything. The best way I have found (that is the way Treyarch made the flinger) was to link a player to a struct and physicslaunch the struct.

Thank you,

setvelocity(x,y,z);

works!

lol.
