Use a time marker and then set an internal clock counter to it using a constrain or 2. It will be accurate.

Have an integer attribute called 'gems'

change attribute timer to timer + 20 (or however much you want)

a) Review all you constrain attributes. Only use them when there is no other option. Use Change Attribute instead as much as possible. (Specially for setting images)

Hmm... these are all good suggestions, I'm mainly focusing on what POLYGAMe said earlier about setting the graphics attribute on the background actor to tile... do you have to set both the horizontal

constrain game.levelTime to game.time - game.levelStartTime

Create a real attribute "10SpawnLimit", integer.

----save attribute game.highScore to HighScore(This is a key)

place a "load attribute" in the highscore scene with the same "key" that you gave to the save highscore (Image)

I have 2 attributes, 1st is current score, 2nd is high score

Make a global attribute called 5seconds, boolean.

I think you can put whatever you want, that becomes the name of your attribute for saving and loading

What do I put in key when saving attribute for current score?

The gun needs to have a boolean attribute called something like 'OKToShoot'.

ANY size - just make sure you have the graphics attribute set to tile, not stretched or fixed (Image)

We removed both width and height attribute definitions in the actor's rule set.

So, my question is... is there any way to add in a background image that can fit this? Maybe by tiling one image over and over again? (Although when I tried doing that I ended up having to drag in the

You could do the same thing with a single constrain. I'm not sure what is better, a timer + a change OR just a constrain, but here goes.

First make an integer attribute then call it lives

create a game attribute called lives (integer)
