I'm a beginner just like you. For my collision, this is what I did:
if sprite hit(hero,ennemy)=1
SPRITE sameenemyspritenumber, posx,posy, imageofcollision
endif
The reason why your outline is black is because you already load the bitmap as an image, then paste it. You can avoid this by using these 3 commands in order: load bitmap, get image, then sprite. I hope this helps man. If you really want to paste image instead of sprite, you can do this:
SPRITE sameenemyspritennumber, posx, posy, imageofcollision
PASTE SPRITE spritenumberuwannacopy, posx, posy
This will get rid of it, but remember that your sprite background have to be in pure black meaning red=0,green=0,blue=0.
