So I have this problem where one entity would play the animation fine on land (like it's supposed to) and when i add another similar entity whereas it is not on land (not supposed to play animation) will not play animation until the first entity renders on screen. 

In which it will follow the same exact animation as the one on land until the first entity goes off screen.

 

Any help would be greatly appreciated. Feel free to clarify if my explanation isn't understandable

You need an else statement in the setRotationAngles method to reset the angles back to default if the entity isn't on the ground as it is using the rotation angles for the one that is on the ground. There is only one Model object which is used globally for all entities so the rotation angles are being shared and only updated on the one which is grounded.

@CHEESEBOT314 Thanks for the reply!

I've already tried that and it messed with the entity that is on ground's animation. Is there another way or do I have to find another method to do it?
