Hello,

I'm having some trouble getting this code to work.
What I'm trying to do:
I'm trying to get a model to follow a path after another model colides with it's trigger. There are 3 models together, the player model, the ball model, and an invisible box I'm using as a trigger to start the ball on its path. I'm using a trigger so I can control which side of the ball the player has to be.

here is the code:
Code:

---

  action Ball_path
{       
	counter = 0;    // there are 23-24 waypoints in path
	temp.pan = 360; // scanning radius horizontal
	temp.tilt = 180;// scanning radius vertical
	temp.z = 1000;  // scanning distance
	result = scan_path (my.x, temp);  scanning for path
	
		if (result == 0) //if the scan finds no paths
		{
			 return; 
		} 
		
		ent_waypoint(my._TARGET_X,1);  //1st waypoint found
		
		while (counter<24)//counts the number of waypoints 
		{
			temp.x = my._TARGET_X - my.x; //distance to next waypoint
			temp.y = 0;
			temp.z = my._TARGET_Z - my.z;
			result = vec_to_angle(my_angle,temp); 

			if (result < 100) // if point found within distance
			{ 
				ent_nextpoint (my._TARGET_X); 
				counter+=1;
			}
                        //move the ball on the path
			c_move(my, vector(temp.x, 0, temp.z), nullvector,ignore_passable);	 
		
			wait(1);
		}
	
	score_basket();	
 
 
}


function Ball_Path_linker()
{       //if impact between trigger and player and the mouse button is pressed
	if( (event_type == event_impact)&&(mouse_left==1) )
	{
		beep(); //test
		ball_path(); //call function for ball to follow path
	}
}

action Trigger_Ball_path
{       //model set for impact event
	my.enable_impact=on;
	
	my.event= ball_path_linker;
	
}

---

summary of code operation (or expected operation):
action Trigger_ball_path is attached to the trigger in WED
action ball_path is attached to the ball
function ball_path_linker is called when an impact between the player and trigger occur.

Does anyone see why this doesn't work.

I'm trying to trigger an action after an impact, but trying to control what side of the model the impact occurs.
Thanks

Add the event event_entity
To your Trigger_Ball_path and the event function:
Code:

---

function Ball_Path_linker()
{       //if impact between trigger and player and the mouse button is pressed
	if( (event_type == event_impact || event_type == event_entity)&&(mouse_left==1) )
	{
		beep(); //test
		ball_path(); //call function for ball to follow path
	}
}

action Trigger_Ball_path
{       //model set for impact event
	my.enable_impact = on;
	my.enable_entity = on;
	my.event = ball_path_linker;
}

---

Thanks for the code.
I tried incorporating this into my code and it's still not working.

In WED the Trigger_ball_path is the action attached to the invisible box model I'm using for the trigger.

The player who colides with the trigger has the following code:
He moves on his own in one direction and the camera follows him.This code works pretty good but I think it is trigger the "Trigger_Ball_path action prematurely.

Code:

---

 
action b_ball_Player_move
{ 
	var temporaryValue=0;
	
 		while(me)		
 		{
	
	   	//animate walk image sequence
			ent_animate(my,walk_animate,walk_percent,anm_cycle ); 
		   	walk_percent += 2* time;
		   
		// move forward
		   c_move(my,vector(3,0,0), nullvector, activate_trigger);    
		   
		//Call function to allow camera view to follow the player around
	   		move_view_3rd_2(); //note: changed variable in function from 16 to 1
	   
	   // if left mouse button pressed turn left
	   	if(mouse_left == 1) 
    		{
    		 temporaryValue.pan = 3;// pan or turn left, if it were -=1 then he would turn right
			 c_rotate (my, temporaryValue, activate_trigger);
				
		   //move in new direction
			 c_move(my,vector(0,0,0), nullvector,activate_trigger);
    			 
    		//clear mouse button setting		 
  			 mouse_left =0;  
  				 
 	   	}
 	  
 		wait(1);
	
		}
 		
}

your corrections incorporated into my code:

Code:

//////////////////////////////

{
	// scanning for path

	temp.z = 1000;

	{

I tried using break points on the last line in the Trigger_Ball_path (line my.event = ball_path_linker;). The breakpoint stopped here but was triggered at the very start of the game. I think the activate_trigger mode ,in the cmove()calls from the b_ball_player_move, tripped this. I set a breakpoint at the functions and neither were called.

any other ideas to help.
Thanks

Ah I got another idea for ya,
why not use vec_dist + mouse_left:
add:
player = me;
in your player's action (at the very top of it)
Code:

---

var counter = 0;

action ball_path
{
  while(!player) { wait(1); } //wait until the player is created
  my.skill2 = 0;
  while(!my.skill2)
  {
    if((vec_dist(my.x,player.x) < 50) && mouse_left == 1)
    { my.skill2 = 1; )
    wait(1);
  }
  
  counter = 0; //number of waypoints
  	temp.pan = 360; 
	temp.tilt = 180;
	temp.z = 1000;
	result = scan_path (my.x, temp);
	
	if (result == 0) 
	{
		 return; 
	} 
		
	ent_waypoint(my._TARGET_X,1); 
	
        //loop for ball to travel path
	while (counter<24)
	{
		temp.x = my._TARGET_X - my.x; 
		temp.y = 0;
		temp.z = my._TARGET_Z - my.z;
		result = vec_to_angle(my_angle,temp);

		if (result < 23) 
		{  
			ent_nextpoint (my._TARGET_X); 
			counter+=1;
		}
                //move ball model along path
		c_move(my, vector(temp.x,0,temp.z), nullvector,ignore_passable);	 
		
		wait(2);
	}
	score_basket();
}

the triggering doesn't seem to work. I'm running out of time so I'll just use the ball as a trigger.

thanks for the help though it is greatly appreciated.
