Legacy GM My Collision Mask won't work??

[Kenzo]

Pretty sure I'm just brain farting here, I'm wondering why my Collision Mask isn't working. I have Precise Collision Checking enabled.
Here's what I have for the Mask Properties:


In the room using this wall collision mask, I have an object with the creation code of:
'sprite_index = sprWall_room_TrueDawn;' Setting the 'Walls' of this room to that sprite.

But when I test this, the character doesn't collide with these boundaries and walks across the room without walls! Please help

May need to use Alpha Tolerance of at least 1 for anything to be considered for collisions.

Do you mind posting the movement / collision code you have?

It's the same thing regardless of the Alpha Tolerance I use.

'Wall' detection:

var maxarg;
var i = 0;

if argument0 = 0
{
    x = round(x);
    maxarg = abs(xSPD);
    if (place_meeting(x +xSPD, y, argument1))
    {
        while (!place_meeting(x+sign(xSPD), y, argument1) && i < maxarg)
        {
            x += sign(xSPD);
            i++;
        }
        xSPD = 0;
    }
}
else if argument0 = 1
{
    y = round(y);
    maxarg = abs(ySPD);
    if (place_meeting(x, y + ySPD, argument1))
    {
        while (!place_meeting(x, y + sign(ySPD), argument1) && i < maxarg)
        {
            y += sign(ySPD);
            i++;
        }
        ySPD = 0;
    }
}
else
{
}

I forgot to mention***
The wall detect and walking scripts have been working fine, it's just this one room that is the oddball***

Hmm, Idk. I usually don't use precise collision. Could it be that the player must also have precise collision checked?

I ended up replicating my previous rooms and just adjusting the backgrounds/collision sprites... Works fine but I'll never know why It doesn't work when I try to make them from scratch. Thanks for your support ;P
