I will try a constrain too.

Great tips, But Instead of changing the linear attributes, you might want to constrain them, because if you don't, then the object is likely to move if it is collided with.

Does your animation stop/pause after 30 frames or continue to loop until it collides with something? If the latter is true, you could just create an invisible actor, constrain it to your animated acto

This case, you have to create 2 more attributes, something like "Block_position_X" and "Block_position_Y".

I think a simple way to do it is using an Attribute.

You could try if touch is pressed change attribute to 1, otherwise, change attribute to 0. Forget the 'otherwise if touch is released'. You could also put a display text actor on your scene and have i

Set the movement with the button, and have the actor move if the attribute is set, and reset the attribute so it is not active until the button is pressed again.

It will be easier to make a game.attribute called gravity & make the accel rule point to that, so you can change all your actors with one game.attribute. this way as you tweak it you don't hav

Wouldn't you just interpolate actor.size.Width/Height x and y over time? Maybe through the use of an attribute like game.size.real?

yeah receives touch pressed, changes attribute to 1,

nop, you must use a constrain to x, y positions.

Change Attribute -> self.Color.Alpha = self.Color.Alpha - (1.0 / ShotCountForCurrentLevel)

There are multiple touches. Choose Attribute in your rule, and then Devices followed by Touches.

On the player I got a Constrain attribute, setting self.Position.X/Y to PlayerX and PlayerY.

(make sure the actor's moveable attribute is unchecked)

Game Attributes needed:

have a game attribute for the players y position (constrain it to player's y in the player actor)

Go to scene attribute -autorotate - uncheck landscape and check portrait

Not on a Mac at present, so I cannot look at TSB's demo. However, in the behavior that causes the teleport...just add a "change attribute" that sets the player "FacingLeft&

Problem #2: On the actor create a rule that when the left key is released, change attribute self.motion.X to 0.
