I'm trying to use code to detect walls and such, but it doesn't work right.

[trim lava]

with Line {

    while (!place_meeting(x,y,O_Wall)) {
        image_xscale += 32;
    }

    while place_meeting(x,y,O_Wall) {
        image_xscale-= 1;
    }

    Person.WallSpotX = x + lengthdir_x(image_xscale, image_angle);
    Person.WallSpotY = y + lengthdir_y(image_xscale, image_angle);
}

This is my code, but it's causing issues like the ones in the video. O_Wall is the blue material. Line is provided an image angle based off a angle from a controller joystick. The lasers come from the eyes and are based off this Line object. 😭

What is the collision mask settings of the laser sprite?

if it's still set to "rectangle" then that could be the problem, the mask wouldn't rotate properly

you'd want rectangle with rotation or precise
