I just finished making a tetris game. When I tested it, the blocks won't show up and it show this error.
you already get your answer in the error message:
Add a CreateRenderer block, maybe in Screen.Initialize event.
===edit===
I just realized you already have this block in startgame procedure, try to move it to Screen.Initialize event.
You can see other users with a similar error have solved it disabling the music:
I'll soon come up with an update that fixes these errors.
Is this only work in 10≤Android
Discontinued.
