This really depends on your exact situation. However, I'm not sure why you need a constrain rule at all to recycle bullets like this. Just set them back to your "shooters" position w

change attribute... self.Random.X (0,359)

Ok, so now I'm assuming by attribute you mean actor moving up or down rather that attribute increasing/ decreasing. Coming what Mark and John have said. As for changing the image depending on Y locati

Change attribute self.position.X (location of exit)

is the attribute an integer?? (must be an integer) (i guess (maybe:P) it's now a boolean?)

i think i know what the problem is! it says that the 'value' of the attribute is '0' which makes the final score '0' its the same if i type in '1'. what should 'the value of the attribute be?'

yeah did you make the score a game or scene attribute? (it must be a game attribute)

ok i am slowly getting there! i have done a attribute for score and that works perfectly! now on the 'game over' scene i have done as you said but when i do a preview the final score says '0'!! any id

very simple, because you have a game attribute, you must make an new actor (highscore?) with display text

just make an attribute score, and make a timer: every 0.1 second (or what ever) game.score+1 (Image)

yeah thanks, only i want to animate the sin so you get if direction is <20 animation picture 1, >20 but <40 animation picture 2 and so on... gives linear y also this direction? (o

oh and with the linear speed y (in this case), can i check also the direction? (because i must make an animation of the attribute and not only up or down;) (must be smooth)

Off the top of my head, you could create another two attributes (say called test and up/down).

how can i check if the attribute is moving up or down (using a sinus on an attribute..)??

I do something like this in BOT... with the shops. Basically... I have an attribute called "TANK-entrance" or something like that. I also have attributes called "Pause&q

You will need 4 self attributes (the ones you add on the actor prototype): NewX, NewY, iAmMoving, howMuchTime.

instead of having the whole game shooting bullets spawn and destroy i have 10 actors one each with a constrain rule , i find this way for recycle my self, i just want to know if you think this is a be

wheever you have your reset or change scene behavior, also have change attribute behaaviros changing your attriubtes to wahtever they are when u start

At the top of the behaviors list of the actor, just add change attribute behaviors to set TargetX and TargetY to the position of that actor.

A lot of attributes are involved.
