Mouse Shortcuts


Move Components Between GameObjects

Avoid going through the process of creating a new component on the target GameObject, copy-pasting the settings from the original one, and deleting said component from the original to "pass it". Just do it directly :o




Optimization


Garbage Collection


Use StringBuilder Instead of "String" += "OtherString"

Did you know that when you use "string" += "otherString" you are generating garbage that needs to be picked up? But did you also know that using the StringBuilder class takes care of that overhead?


Optimize Calculations


Edit Collision Matrix

If your game involves stuff colliding with one another, you might want to limit which things can collide with which via the collision matrix.

With some good planning, you might even avoid having to make tag comparisons, and other troublesome tasks.


Development Time Optimization


Built-In Primitive Sprites

Don't go out of your way making sprites like squares, triangles or circles, use those already built in Unity.

Save your time, and even memory, with this small, efficient simple sprites.

Documentation


Help URL

Do you have your own documentation site for your things? Or have you ever wished you could keep a script reference next to you? Because, the HelpURL attribute allows just that.


Documentation URL
