Hi,

Have another question:
If I move a sprite completely off of the screen does AGK2 stop drawing the sprite?
(I ask in terms of overall game performance)

Thanks!

i think the drawing buffer is only the visible part, means outside there is nothing where it can set pixels.
but collision handling should be also off screen.

I'm with Markus, I think once it's off screen it's not longer drawn. But it's probably still included in the collision operations (if you're using that).

Hi,

Ok, thanks for the verification.
Project is a puzzle game so there are no collision operations being used...

Hi,

This is not correct.
On the [How To Play] animated screen if I let it run for 20 minutes on Android the Frames Per Second slowly goes down.
There are alot of sprites active, but only about 15% of them are on the screen at a time(while others are completely off of the screen).

Let me hit this with a hammer and if I can't fix it I'll come back and ask for help.
Thanks!

It could be for a number of reasons.
If you're running for 20 mins, adding sprites and never deleting sprites that are not used, you'll have problems irrespective of if they are being drawn.

Hi,

I think we are OK now.
Deleting the colored box sprites after use seems to have stopped the performance drain on Android.
(I have a Frames Per Second display to see performance)

Thanks!

If it was a slowdown due to drawing, you'd notice it immediately not over time. Sounds like you were slowly consuming memory. How often were those colored boxes being created?

Hi,

Everything is ok...
The screen which had the performance issue is below.
It was the [How To Play] animated screen which shows player how the game works.
(the colored boxes would change every 5 seconds and then matches of 3 would disappear)

Thanks!
