Mouse over Object size

I am work(away.info)'ing for a month in England..

AND i forgot my .Capx in Denmark -_-

EDIT: I found the Error and fixed it, but then another question came up because of that.

Old---------------------Old-----------------Old-------Old-----

How it should do

And here is the Capx of what the version does I have made so far:

new

The problem I want to fix is the Mouse. I can't remember how, but I did NOT do it the way I have done in the new Capx.

The only Blue Tile I want visible is the one the mouse is over.. But in the new one, i had to use a distance to prevent it from making several visible if overlapping at an edge. This was not a problem in the Old Capx...

Please help me locate the error :)

So now i simply tried to put:

Mouse over Object (blue)

And it worked!

But how? Is it because the mouse.x and mouse.y are 1 "pixel" so it simply cant overlap two? And because I used the sprite instead it was overlapping more then 1 "pixel"

Yeh that makes sense.. I shouldn't post this when I am answering myself lmao...

Move to junk topics ?

Wait, I got a question that is related to this:

Does it matter how I build up around the Every Tick?

Can i get in trouble for using

Every Tick - Set Invisible

Without setting up parameters for when NOT to set invisible inside the every tick?
