Constrain

The velocity rule may help in performance down the road when more is going on in the scene...no need to constrain if things aren't moving (and if GS' rule parsing is working properly ;-p ).

constrain attribute:

What did it do to the fps? (with the timer and the constrain)

constrain attribute self.rotation = vectorToAngle(self.motion.linearVelocityX, self.motion.LinearVelocityY)

Constrain self.rotation to VectorToAngle (self.position1X-self.position2X , self.position1Y-self.position2Y)

Constrain blah blah

Create a global boolean attribute called something like FishTankIsDestroyed

If there is a fish tank on the screen and a fish inside the tank and the constraining attributes keep the fish in the tank, when the tank gets destroyed why does the fish stays where the tank was dest

It works similarly to the Movable attribute, which is a flag that tells the processor whether to add the Actor into the physics system or not. If the Actor is NEVER going to be seen, make sure to turn

In an actor's attribute panel...in the Graphics list, there is a "Visible" setting.

the seed-clone relationship. Also any custom attribute you make, or any attribute for that matter... Basically you can change anything in the Instance on the left side of the Editor (anything NOT und

The other one was hitting the CPU pretty hard. It used to work by having a Constrain Attribute for each digit, as well as 10 Rules per digit to set the image.

I rebuilt the demo to set the image using concatenation as opposed to having 10 separate Rules. It still needs a Constrain. I have a 5-digit score and on my 3GS, the frames rarely drop below 60 - even

If you're using my demo for the score, it's not so much the number of Actors, as it is the Constrain Attributes. Currently each digit requires 1 Constrain.

I imagine you could have 4 integer attributes - position1X position2X position1Y position2Y

Here's one thing I noticed... if you use the joystick angle and set your actor to rotate that angle, it gets confused past 180 degrees. (Constrain to that angle works much better.)

I'm trying to find a way to detect if an incoming enemy is on screen or not. My game is a side scroller, my enemies come from the right outside the screen. I tried to set up a zone covering part of th

I'm having great difficulty (1) spawning an actor from another actor and (2) determining the coordinates for the positions of X & Y in the Spawn Attribute panel -

Use an actor attribute called "actorID" to allow clone actors respond differently depending on their ID. Once the actor is in the scene, modify the actor ID number within the scene t
