Gameattribute PlayerX is constrained to the player actor's position X.

Each actor "wall" as an attribute "selected" which change between 0 and 1 each time it collide with my player. Only one can have the value 1.

Create an integer self attribute call it what ever you want .. "self.xx"

However, your constrains are very limited.

This is still relevant today, tables don't have a row zero, so it causes issues when it has references to attribute that start at 0. Not anything wrong with the tables, this is the intended and correc

Also, if tables are still causing crashes, I'm assuming the above method by @The_Gamesalad_Guru is set with a self.row integer attribute starting at 1? Or does the attribute type/start matter?

Attached is a very quick constrain example (file attached below) for the rotation element of your question - click to rotate - I'll leave the flip element to someone else as all my questions will prob

The second square is made up of two actors, however I don't know how to constrain Actor2 so it would move accordingly.

So, I want to constrain Actor2 so when I rotate/flip Actor1, Actor2 moves accordingly.

To @ForumNinja : There shoud be a fixed thread on the forum with links to the most basic video tutorials / cookbook. Like, doing off with things like "how to make an attribute" etc.
