[Supereor]

Hey all, first post on the new forum! Looks great, anyway I'm having a bug that I cant figure out I have this character and when you use an ability it will "stab: the spot right in front of him now it work. BUT it doesn't work when I hold up and left or up and right, it work with bottom and left and bottom and right. I'm not sure why heres the code

//The second abiltiy Slash
    if(keyboard_check_pressed(ord("E")))
    {
        if(!slash)
        {
            alarm [1] = 80;
            instance_create(x + lengthdir_x(8, image_angle), y + lengthdir_y(8, image_angle), obj_slash);
        }
    }

this is just a snippet from a larger step event but the other stuff is irrelevant to this.

Are you using a keyboard or a gamepad?

If a keyboard, you're probably a victim of keyboard ghosting. Try changing your input keys. If that makes it work, it's almost definitely a ghosting issue.

The only way around ghosting is to give the player the ability to customize their inputs (since which keys ghost vary from one make of keyboard to another), add gamepad support, or rewrite your game so that the player will never have reason to press more than 2 keys at a time.
