Hey!
I've tried all ways which I found on this forum but nothing works. c_setmin_x worked but I don't like a size of bounding box after using this, so I've tried to set it manually by my.max_x but nothing happens .Here's my character's action code:
action character()
{
............................
............................
set(my,NARROW);
set(my,FAT);
wait(1);
my.max_x = 2;
my.max_y = 2;
my.max_z = 2;
my.min_x = -2;
my.min_y = -2;
my.min_z = -2;
while(1)
{
............................

Code seems to be ok, but the bounding box stays unchanged.
I also used debug mode and I saw that player.max_x/y/z changes correctly but 3dgs seems to don't give a shit about it cuz bounding box is still the same .Please someone help me, because I will soon freak out.

NARROW , FAT this is eflags, you can not use "set,reset" for setting this flags, try this
my.eflags |= NARROW;
my.eflags |= FAT;

Sweeet

Thank You Very Much! :]
