Detailed Description

Transform struct

This is the struct that represents the position, rotation and scale of a node among other things. The position is stored as a Vector2, and the rotation and scale are stored in a transformation matrix.

There are a lot of operations you can do to a Transform:

Transform myTransform;
myTransform.position = Vector2{0.0f, 0.0f};
myTransform.setScale(Vector2{3.0f, 3.0f}); // make it 3 times as big!
 
Logger::log("{}", myTransform.getAngleRadians()); // print out the angle of the Transform in radians!
myTransform.setAngleRadians(20.0f * (3.141592653f / 180.0f)) // set the angle to 20 degrees in radians
 
myTransform.rotate(-20.0f); // rotate it back 20 degrees, and now the rotation will be 0 degrees.
