If "mouse button" down change attribute game.action to true

the every timer's set of functions, a Change attribute, so that when it reactivates on the next loop the expression changes. Is that impossible?

Change Attribute: game.newAttributeX To: self.Position.XChange Attribute: game.newAttributeY To: self.Position.Y

For random movement within a range, create random movement rules (for example, by using a custom timer) and constrain the actor's position:

Sure. I assume you already have a rule condition for game over (e.g. game.gameOver=true). In that rule, have a change attribute to change game.score to game.score+game.bonus.

The add/remove row attribute does not work well. I have a table with 15 rows. But sometimes a couple, if not all, of my 3 object is just going straight to the bottom of the screen (value 0). Any ideas

Well, for the bullets, you should be able to use a timer with an attribute that is determined within the timer as random(3,7) for the value if you don't need any specific variance or patterns, so that

Sorry think I worked it out, make two new attributes and then do change attribute in the second actor, self.postion.x to game.newattributex, then I can link the data back to the expression in the firs

Also play testing I discovered a bug on mini-Game 2 Plasmag miner once you complete level it want advance to next level somehow I set a attribute back to zero not sure how that happened anyway already

Try a three game level attribute and use Constrain to record the hero's rotation position, position.x and position.y and use these in you enemy rules to determine the relationship between the two and

I have tried setting an attribute called 'PlayerFront' so that when the left button is pressed the 'PlayerFront' attribute is set to the left side of the player (I used the expression: self.position.x

Create a self Boolean attribute called nextscene then at the same time as your play sound behavior change self.nextscene to true.

Give each letter actor a self attribute (text) called self.myLetter. Manually enter the letter in as the default value for each actor. Then add these rules:

There may be an attribute you've forgotten to reset if it's working once but not after restarting.

I have Save and Load attribute. Do they work properly when I test my game through TestFlightApp.com ?

Then get a change attribute behaviour and change self.motion.angularvelocity to 50 (change this number to increase the angle of incidence on the curve.)

You can alter my demo to if game.coins is greater than self.Price and touch is pressed change attribute character selected to <#>. Just replace the Characters Purchased attribute with yo

No problem! I don't know of a tutorial that does exactly this, but you'll see the practice of saving attributes in almost every tutorial out there.

Create two real attributes called self.startWidth and self.startHeight (what you call them doesn't matter but they should be of type Real).
