Does a video game designer have to take math classes

yes they have to do :

Math plays a large part in video game design. You need to take classes covering parametric and implicit linear equations, derivative and integral, and implementation and application of linear algebra. These skills allow you to create and manipulate two dimensional assets in video games and interactive simulation design.



To apply three dimensional geometry to video games, you also have to take programming game physics. This involves matrix representations of transformation, perspective projection, rotational physics and calculation of mass properties.
