Today I worked out the glitches with the spider enemy. First I got the sphere collider on the spider to stop registering as a physical object by trying some things that had been applied to some of the other objects in the program. After that I managed to make the enemy follow and attack you(I kind of came across that randomly). Then I edited a script I found in a tutorial that Jake gave me so that the spider did damage automatically when you were in a certain proximity of it. After I had done all of that it worked flawlessly for three or four replays until a random glitch basically made everything I had coded become useless.  >:-(
