That means that you're either not saving or loading your attributes correctly. It's important that the key you use is EXACTLY the same in both the save and load attribute behaviors.

The constrain attribute is preventing you from adding any to it. You don't need the constrain. Take a look at this example, it's just one way to do what you are trying.

I'm not really sure what 'constrain the 0 to 0' means, but you can use a rule to check whether your time value = 0, and if it does then add X to that value.

* create a new game attribute called "image1" and set it to 1

attached is an example. If I constrain the 0 to 0 I can not add to it either.

I have been following this tutorial below, everything work great, after finishing level 1 -> level 2 unlock, go on... But whenever I shut down the game and reopen, the unlocked level gone and n

I added a self.ballAlmostStill attribute to the ball actor and if the ball speed is less than 0.3 then I change the self.ballAlmostStill attribute to true. Then I added a 1 sec timer that says that af

ok with this interpolate attribute what are the settings to scale the actor over a 1.5sec duration??

No no, this is not an "animate" feature. You'd simply do an "interpolate" attribute, and set it make your changes within. (Image)

Alright, figured it out. Put a "Change Attribute to Game.BronzeStar to False" in the "Else" section of when the Player Collides with BronzeStar actor.

Hmmm, very weird. I even tried setting an attribute change for when the player pics up the star.

without to put the score attribute equal 10

Because the score attribute is 0 when it starts it is immediately changing the score to -10.

I use only integer attribute equal to 0, and i don't have index attribute because i use windows.

Create 2 real attributes, one EnemyX, one EnemyY

I know you're supposed to constrain but every time I pass that line the enemy just jumps right on top of the hero & It just ends up looking bad. Maybe because I constrained the hero's position

@bjandthekatz should I make a new actor and constrain it to the enemy? What should I constrain it to? The enemy, the attack button, or the hero?

Constrain the enemies position to 2 real game attributes, EnemyX and EnemyY.

When touch is pressed: make attribute true
