Entity speed is a Vector2f #91

The Vector2f class in org.newdawn.slick.geom is a Vector. Meaning it has a speed and a direction. See http://www.physicsclassroom.com/morehelp/vectdirn/practice.cfm

Entity.speed is not a Vector and thus should be changed to... a Point class? or dx, dy

But a Vector2f is very helpful because you can normalize it (used in some places), scale it, add and subtract other vectors. You're right, basically speed would be just two values, speedx and speedy. But as I mentioned, it does make sense to use a Vector2f for speed. Maybe the name doesn't match it properly because the speed somewhat contains direction and speed.

ok, I'm very new to Vectors and the Vector2f class. If you need it it must stay. I only use speed.x and speed.y
