since when you have a error , the error it self can due other errors , and if you not press esc quikly you not see the real error in the consolle.
so , i want to stop the game engine at the first error, running endGame():
import bge if errorHappen: #how replace this line? bge.logic.endGame() def buggyCode(cont): #entry point 1 = error
it seem that you have to write a class , but not know how write it exactly .
