You need to create a Boolean attribute in the Rustler called "killed".

I tried that. What I did was this: Created rule when actor collides with ball I added a change attribute. self.Motion.Linear.Velocity.X to 0. Same for Y. Doesn't seem to work. Also, What do you mean &

could you use an attribute to control the rustlers movement, when the ball hits him it changes the movements attribute to false or 0, effectively stopping the rustler moving?

It could be as simple as when actor is touched, and acceleration or move attribute.

Custom actors would only need to be a set of .h/.m/.xib files that a developer would have to build with a simple get/set attribute I/O structure that GS could access; this would allow a developer to a

/ framerate) that displays all (or selected) attributes and their values?

I created a few global attributes - shoot, x, y

Haven't tried this, but here is what I would do. Create a game attribute called targetX and another called targetY (set these to real). Create a third game attribute called shoot and set it to boolean

I would make your Scene.level attribute global as well - that way all Actors have access to it. I would get rid of scene.level, and just make a similar level monitor.

I think a really helpful addition to GS (for me anyway!) would be a Boolean Attribute for Actors called "Affected By Gravity".

In each scene I put an attribute called level, and I want to just check "If scene.level = 1, change scene to next level"

Constrain an invisible actor to the sound area. When the player collides with the invisible actor have it play the sound.

You would have to have two attributes, homeY and homeX in the actor.

If I constrain an integer to the real number, won't that just cleave off the decimal? In essence just a floor?

Or you can round a number by constraining an integer type attribute to that real number value.

In the enemy ship, create a new enemy ship attribute called initY

in it's simplest form, just create an attribute called enemies & anotherone called maxenemies

Change Attribute: game.evenOrOdd To: myNumberToTest % 2

Create a boolean attribute called "left", and leave it at 0.

I can see I'm gonna have to watch a few of the videos as I'm not even sure how to create an attribute (Image)
