After working with App Inventor in several school projects, I decided to start my own Christmas-style game as a personal project. The objective of the game is to drop as many presents as possible without hitting any of the enemies. I did this with a canvas and sprites that move as the acceleration of the phone is changing(which lucky for me seems to be all the time), each target you drop a gift at gets an enemy to start moving, there are 6 enemies in total at the moment. So for the first 2 targets, you hit the enemy movement is fine, once you hit the 3rd target the game starts to lag quite a bit, when you hit the 4th target the game lags even more, finally, after hitting the 5th target, the game completely stops and crashes. This is after compiling the app and downloading via QR code, the AI companion is so much worse. My device is quite powerful and is not the problem so how should I fix this?
This is hard to diagnose without seeing how you manage your lists of sprites
and how you move your sprites.
Also, are you taking advantage of generic collision events to cut down on block count?
If you post your exported .aia file, more ideas can emerge.
Thank you for attempting to respond, but I was able to cut down on the lag by using the clock component to update every frame.
