Questions & Answers

Hello,
I am creating 2d Platformer and I want to have a lot of trees, mushrooms, leafs etc on Level.
Is it ok to put them as normal Sprites? Can Scale them ? Or it will cause a lot of perofrmance lose?

I already use system that enables some part of the stage and disables previous one, so not so many gameObjects be enabled.

If you’re making a platformer than I highly recommend using this for creating levels. http://www.mapeditor.org/ It lets you create tile based levels and export them as one prefab. You will also need this program to export the maps you create into unity. Get Tiled2Unity
