Hi James. If you're copying an pasting between projects, there might be a reference to a non-existent attribute or actor which could cause the problems you're seeing.

you can change the density of the object that doesn't move. Or you can make the object not movable. Or you could constrain the position of the actor that doesn't move to a specific point.

You could spawn an actor in a certain area and give it velocity with a random angle. To constrain it you could create invisible rectangular actors and use 4 of them to make a "fence"

Doh! I fixed it.... looks like I have old code (before Constrain Behavior was introduce) I was only updating my X/Y every .5 seconds in my Player! So I just converted my Change Attributes to Constrain

Constrain Atribute: self.Position.x TO game.PlayerX

I then created an Actor called playerShield that would be spawned when the shield was enabled. The code in the playerShield contained the animation sequence with a Constrain Attribute for the X and Y

1) Create a game boolean attribute (I called it jump) check that it is true

--Change Attribute: Touchleft is true.

--Change Attribute: Touchleft is true.

Change attribute, game.moveleft to true

Hello, I want to change the camera size in SCENE to 320x480 but its grayed out and I cant change the attribute....how come its grayed? Please help. Thanks.

Change attribute Weapon to 2.

Rule: if attribute self.postions.x >=425 then

Constrain Attribute [self.Motion.Linear Velocity.X] to [game.Mouse.Position.X - self.Position.X]

As far as keeping the enemy from moving, the only solution I've found so far is to play with the density attribute under the physics panel, the more dense the actor, the harder they are to move when s

They also don't have to have the Collide behavior. That is only for physical collisions. The event detection of overlaps or collides will still activate if they strike.

what attribute did you put on your character actor? do you have a drag or rotate behavior in your actor?

Here is one alternative. Think recycling. Have these actors off the visible screen & when battle starts put in a change attribute that set X to random(0,480) & Y to random(0,320). Or w

You may need to set up a rule that changes the attribute color (self.color.red) AND a custom variable for each color (self.enemyrRed) so you can FLAG it when it is true or false.

It's pretty simple. All I do is constrain the position of a ship to two real attributes, and have a missile accelerate towards that location.
