You might be better asking over in the Scripting section of the Unity3D forums; http://forum.unity3d.com/forums/12-Scripting But you'll want to add these lines to your OnCollisionEnter function; score -= 1; UpdateScoreText();
Right now I have score code that updates by 10 when I click on the screen but I want to have it so when my character collides with the vase the vase disappears and it updates the score. Have no idea if all this needs to be in an Update function or what. Someone please help.
