as JamesBoucher said, it's probably a rule referencing an attribute that was removed or a rule that was copied from another actor that uses a custom actor attribute.

so, load the saved high score into an attribute

just create an actor that resets everything on one of those screens. you'll need a change attribute for each attribute you want to change.

You have your attribute: HighScore

I have a game over screen when you die that displays your high score, I thought I could put the save attribute on that and on the main menu have a load attribute but its not working and I'm not sure i

Save attribute and Load attribute.

Sometimes I get a crash when I press play. I've found that I have logic being used in the scene by an actor with an attribute that no longer exist. Fix or remove the attribute and it will work.

You have now to correct the collisions, they're very bad. And improve all the editor and the game engine too.

What I do is have one boolean game attribute for each button.

2 boolean attribute created, rotateleft and rotateright

Attribute Saving

Save Attribute and Load Attribute behaviors

Save Attribute

I made an actor attribute for the player called 'on ground'. When the player collides or overlaps with a platform and the Linear Velocity. Y is below 10 yet higher than -10 it turns the attribute 'on

What I do is pretty simple. I have 2 actors, a player and a bullet. In the bullet actor I created two custom attributes (X and Y). I also created three global attributes, Touched, X and Y.

The man and the mans hand are two separate actors and the way I put them together is made a global attribute that was constrained to the player x,y. The hand x,y was constrained to those attributes +

Also how do I constrain the distance it goes? Like I only want it to go out a few units.

O.k. but where IS the attribute SPEED of the Animate Behaviour? I cannot change it with a variable because I cannot "see" it.

I know that I could create different rules with the same Animate Behaviour in them with different fps that are triggered by an attribute. But can I directly access the speed of an animation?

If the actor 1 doesn't rotare It's simple (create two game variables, constrain these two variables to actor1 x and y coordinates, constrain actor 2 position to the two variables),
