Hi All,

I'm having some trouble with c_move  and negative values, and I'm hoping this is a really simple oversight on my part because I'm starting to think I'm better off working on my own collision-detection then relying on this inconsistent function.

I made a level in WED with a ball and a paddle (both MDL models) and attached a script with actions for both models, then built the level.  

Paddle Action Code:

action move_paddle()
{
var pspeed = 4;

while(1)
{
If (key_a)  //move left
cm_move(me, nullvector, vector(-pspeed*time_step, 0, 0), GLIDE);

If (key_d)  //move right
c_move(me, nullvector, vector(pspeed*time_step, 0, 0), GLIDE);

wait(1);

}// end while

}// end action


The 'd' key works fine (moves to the right), but the 'a' key does nothing or will randomly move to the right too if I toggle the bbox flag in WED.  I've also tried replacing the pspeed variable with the value "-4" in the c_move function and I get the same results.  Same story with the ball action, won't move if a value is negative.

Most other c_move topics I've seen involve setting one of the _PASSABLE flags but I've tried a few of those too with the same result.

Can anyone help me with this?  There has to be something I'm missing...
