My player shoot the bullets 90 dregrees off

Question

This may be an easy task, but I cant figure it out. This is a 2d game using the LWJGL library. I've created the player using openGL and the bullets with openGL. The bullets go 90 degrees more to the right.

Classes:

Game class

Player class

Bullet class

Update class(not important)

Render class(not important)

So, how can I fix that? If its only adding 90 degrees can you tell me how?

Thanks

LWJGL使用弧度，因此在转换为弧度之前，您需要将度数加90。
