Hey,

i'm having trouble with preventing my ai (zombies) from colliding with other objects (pickups, walls and obj_player)

i just started with gamemaker so i really dont know what to look for, ill post my codes below. If you need to see other codes please ask.

Thanks in advance

Zombie step:

//States

script_execute(state);

//Collisions

if hspeed!=0

if !place_free(x+hspeed,y)

{

if hspeed>0 move_contact_solid(0,hspeed)

if hspeed<0 move_contact_solid(180,-hspeed)

hspeed=0

}

if vspeed!=0

if !place_free(x+hspeed,y+vspeed)

{

if vspeed>0 move_contact_solid(270,vspeed)

if vspeed<0 move_contact_solid(90,-vspeed)

vspeed=0

}

//Move to direction

image_angle = direction - 90;
