What the game has (so far)

so far the game has a game over screen, title screen, Player movement, + animations Sky box, etc.

but one of the those things is not enemies or more well functioning ones I'm currently trying to get 2 things done the sword's code and animation and the enemy the enemy is so annoying because it just doesn't work it works perfectly 

until I try to add a floor checker when then the enemy just breaks and the code stops working and its annoying I also tried looking up tutorials but for some reason their no real help with this
