I have a flying bird that are supposed to turn when it hits a invisble wall.
But the bird is stopping when it reaches the wall.
The wall is a mdl. And I have set it to invisble.
Why isent it "reacting" to the wall. I have also tried to have it visible and no reaction. The bird only stops right infront of it.

here is the code I am using.
and yes I am using
my.enable_block = on;

Code:

---

define speed_x,skill21;
define speed_y,skill22;
define speed_z,skill23;
 
function hit_event_10()
{ 	
if(event_type == event_click) 	
{  		
my.flag1 = on;		
highscore = hitvar1;		
wait(1);	
}		
if(event_type == event_block)	
{		my.pan += 180; //turn around	
}
}
action hit_object_10
{	
my.enable_block = on;	
my.enable_click = on;	
my.event = hit_event_10;		
my.speed_x = 10;	
my.speed_y = 0;	
my.speed_z = 0;			
var speed[3];		
while(my.flag1 == off) 	
{ 		
vec_set(speed,my.speed_x);		
vec_scale(speed,time);
ent_cycle("walk", my.skill1); // animate the bird
		my.skill1 += 3 * time; // animation speed 
		my.skill1 %= 100; // loop animation 				
c_move(my,speed,nullvector,ignore_passable);
  
wait(1);	
}	
ent_remove(me);
}

I think you should use event_entity (for mdl) instead of event_block (this is level-geometry).
Perhaps you can use bounce to change the angles?!

I found this in the manuel:
Collision with a surface of the level during a MOVE instruction. The entity must not be PASSABLE and it's PUSH value must be 0 or less. On start of the EVENT function, the vector NORMAL is set to a direction perpendicular to that surface, and the vector BOUNCE is set to the direction into which the entity would bounce off.

So double check your push values, my.push for the bird should have a 0 or less value

Thanks for the try to help me. I had to remove al my mdl walls and have the bird fly inide a box..... then it worked fine...
