    Need help with game math (Angle/Points)


    Hi guys,

    How do I translate an angle to a direction in coordinates.
    For example: 135 deg tranhslates to (1, 1)
    Will move it bottom right.

    Thanks in advance.

    What your asking is relatively simple; start with a point at (0, 1) and rotate it the number of degrees that you want for the desired effect.
    Code:
    int degrees = 135;
    
    float x = -sin(degrees);
    float y = cos(degrees);
    The above example uses a simplified version of the two dimensional rotation formula since x is known to be zero.

    Also, in your above post don't you mean 135 degrees would translate to (1, -1)?
