Hi, I want to learn how to create cameras like resident evil game.
I've found a real intresting code in the AUM 42 ( link )
I've donwloaded the file from there and copy - paste the file from the advcamera folder to gamestudio/work folder.
The problem is: I don't know what script i have to include, cause the action player_prog is missing.
I've also tryed to create my action
Code:

---

 action pg {
	my = player;
	while(my){
	
	if (key_cul == on) // press and hold the "Up" arrow key to move
		{	
			my.pan -= 3*time_step;
			ent_animate(my, "walk", 5, anm_cycle); // animate the model (use "walk")

		}
		if (key_cur == on) // press and hold the "Down" arrow key
		{	
			my.pan += 3*time_step;
			ent_animate(my, "walk", 5, anm_cycle); // animate the model (use "walk")

		}
		if (key_cuu == on) // press and hold the "Down" arrow key
		{	
			c_move (my, vector(5, 0, 0), nullvector, glide);
			ent_animate(my, "walk", 5, anm_cycle); // animate the model (use "walk")
		}
		if (key_cud == on) // press and hold the "Down" arrow key
		{	
			c_move (my, vector(-5, 0, 0), nullvector, glide);
			ent_animate(my, "walk", 5, anm_cycle); // animate the model (use "walk")
		}
	}
}

But it doesnt work, the player stay there and doesn't move.

Someone can help me?

Here are your errors>>>

1) your setting my=player; >>> should be player=my;
2) To turn left >>> my.pan += 3*time_step;
3) To turn right >>> my.pan -= 3*time_step;
4) You need to place a wait(1); after the 3rd from last curly bracket.

And make sure you have attached the action to the player entity in WED.

the player move
(there is also some problem with the animation that i will try to fix later)

But there is a problem, the camera doesn't change.
the code in now this:
Code:

view adv_camera{}

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

define cam_number skill1; // use different numbers for every model
define cam_range skill2; // sets the detection area (sensitivity)

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

	level_load ("office.wmb");
}

function set_camera(number);

This is all from aum 42, the thing tha i haven't undersant is how the action detect the player, cause this doesn't work
