2D toolkit incrasing performance

[singh029]

Hey! So i wanted to create multiple levels for my 2d platformer. The only thing i was afraid of was the performance on mobile devices.

Is there a way to turn off (setactive = false) the tiles in a tilemap when off screen?
i.e. Pooling
Is there a way to access each tile programmatically or would that cost too much?

Thank you!

It shouldn't be necessary. tk2d splits up tile map into chunks, and unity will cull those chunks when out of screen. It doesn't deal with 1000s of game objects at a time, but merges 1024 tiles into 1 chunk by default.

Sweet! what if i set a prefab inside one of the tiles in the Data tab of the tilemap? do those also get culled?

They will get culled, but those should probably be turned off and on - check the tk2dTileMapDemoCoin code, it uses OnBecameInvisible, OnBecameVisible to turn off the animator when out of view
