Legacy GM Trying to make it so the only walls that are visible on screen are in my player's line of sight

[AngelofGamin]

however, I seem to run into a problem where all the walls are just permanently invisible when i start a room

this is the code I used:

if collision_line(x,y,obj_player.x,obj_player.y,obj_wall,1,0)
    {visible=false;}
        else
        {visible=true;}

Also, here's more or less an illustration of what I'm trying to achieve:

it looks like you're just referencing one instance of obj_wall - you need to use "id" if this code is within the step event of the wall object

 

[Catastrophe]

Your last argument should be 1 or true, not 0: You don't want want the walls to count themselves or they will always collide:

"notme Whether the calling instance, if relevant, should be excluded (true) or not (false)."

You may even have the 1,0 backwards, as I doubt you need precise collisions on walls.

@Rob I'm assuming obj_wall is just an object_index, so I think it's correct
