Game Going Crazy [Solved]

Hey guys! I'm having some difficulties with my game. I've put comments into the .cap to show where the problems are. Going left bugs up my screen and makes everything flash. Also, I can not figure out how to make smaller objects set their Z layer behind bigger objects. Apologies for my coding in advance. All suggestions or alternatives are appreciated!!!!

The flickering if from multiplying by a negative number. instead you should multiply by 0.9996. of course you really should be adding and subtracting from position to move most of the time. For the sorting use "for each ordered" with the barrel width.
