Warning notification how do I fix the problem?

I have a Assets/BulletUnity/Examples/Scene/BulletSharpDemos/ConvexDecompositionDemo/ConvexDecompositionDemo.cs(49,32): warning CS0219: The variable ‘childshape’ is assigned but it’s value is never used and here is the code line:

CollisionShape childShape = compound.GetChildShape(index1);

how do I fix this and if I just delete this part of the coding (and also with all other warnings such as this one), will it negatively have an effect upon the game performance of any game that I’m developing I really need the help here.

It is just a warning to tell you that you have assigned a variable but never actually use it (on the right hand side of an expression or pass it to another function). So you should remove all such variables that you never use… it will give you better performance :slight_smile:
