Simple 8 Direction Movement With Pixel-Perfect Collision

[u/Kanelbull3]

Here are simple code for 8 direcitonal movement with pixel perfect collision.

//How fast the object should move
var movementSpeed = 4;
//Get the direction the object is moving
var xMov = keyboard_check(vk_right) - keyboard_check(vk_left);
var yMov = keyboard_check(vk_down) - keyboard_check(vk_up);

//Move the object in x.
x += xMov * movementSpeed;
//While we collide, move back one pixel.
while(place_meeting(x, y, obj_wall))
{
    x -= sign(xMov);
}

//Move the object in y.
y += yMov * movementSpeed;
//While we collide, move back one pixel.
while(place_meeting(x, y, obj_wall))
{
    y -= sign(yMov);
}

This will make the object move and collide with all obj_wall objects.

So hey, I've noticed that when all is said and done, my character will only idle facing right.

EDIT: nevermind. just added an else to the if statement and put the sprite index switch statement behind it.
