No it doesn't have to be the same size: basically, if you use Change Image behaviour or Change Attribute self.Image, in both cases, if the changed picture is a different size, it will be forced to the

when actor receives touch pressed change attribute touch_press =1

I think the problem is that your constrain to touch, and interpolate to target rules are interfering with each other. You see, even though the movable actor has changed it's position, and it appears a

I want to save the reaction time as an attribute. I have created an attribute called ReactionTimer and GameTimer.

but that makes me wonder why the self.unlocked attribute is not updating though... because the unlock attribute is constrained to the row and column of the character and it clearly says false but its

The way I do that is to give each instance of the character actor a unique value, for example self.position. After you add an attribute to an actor's prototype, you can double-click each instance on

for some reason though im pretty sure its the self.unlocked attribute thats not acting right... any advice @tatiang?

A second way would be to just have only the amount of items that you start with in the table; then when an item needs to be added or deleted, you use the Add/Remove Row behaviour (as well as Change Ta

----the following loop is outside of the change attribute for changing the name of the item, and doesn't use the modulus, because I couldn't get it to work using that method, i.e in the expression edi

It seems like you're asking how to compare a table cell value to an attribute. But you already asked that and I answered it here: http://forums.gamesalad.com/discussion/comment/375861/#Comment_375861

i try many numbers on the y attribute but nothing changed.

the power up. I made an integer invincibility attribute which says that if the actor touches the powerup, "set invincibility to 1 (original is 0) and tried using a timer, but it doesn't work

You must have a rule that says If [some condition] do change attribute game.enemy actors to game.enemy actors+1. What does that rule look like?

If starting as a rule looking at an attribute you cant insert the modulo function.

You're using the same key name for all of your attributes. Keys can only save one value at a time. You'd need a unique key name for each attribute. I usually use the exact attribute name like this:
