I am trying to learn how to make a worm game. And I found a tutorial here in the forum. I follow the tutorial and I get the error that says this:

unknown parameters
snake_cor_x
snake_cor_y
snake_pan

Can someone tell me why this is wrong and how to fix it.

the errors comes from this part of the script
Code:

---

 action worm_move
{ 
	worm = me;
	my.narrow = on;
	my.fat = off;
	torso_nr = 0;
	array_torso[torso_nr*4+0] = handle(me);
	my.id_handle = torso_nr;
while(1)
	{ 
		torso_nr = my.id_handle;
		my.pan %= 360;
		camera_worm();   // Kamera
		time_off += 1 * time;
		if (key_cul == on && my.pan != 270 && time_off >= time_set)
		{
			my.snake_cor_x = my.x;   // X-Wert bei Richtungswechsel
			my.snake_cor_y = my.y;   // Y-Wert bei Richtungswechsel
			my.pan = 90;                    // Pan-Wert vom Worm
			array_torso[(torso_nr)*4+1] = my.pan;    
			// Verwaltung im Array wird noch nicht verwendet
			array_torso[(torso_nr)*4+2] = my.x;     
			// Verwaltung im Array wird noch nicht verwendet
			array_torso[(torso_nr)*4+3] = my.y;      
			// Verwaltung im Array wird noch nicht verwendet
			my.snake_pan = my.pan;	// Pan-Wert bei Richtungswechsel		
			time_off = 0;   // Ruhezeit für Richtungswechsel
		}
worm_speed = 10 * time;
		move_mode = use_box;
		ent_move (worm_speed, nullvector);
		wait(1);
	}
}

Try making all those variables:

var snake_cor_x
var snake_cor_y
var snake_pan

And place them at the very top, for starters at least and hopefully the errors go away.

You need to define those variables.

Something like:

define snake_cor_x, skill50;
define snake_cor_y, skill51;
define snake_pan, skill52;

thanks that did the trick.
