 The collision type is the type of collision check that clld will use.
 
+The Cursor width, and height are just that.
+
 Cursor x, y, and z are the coordinates of the cursor, which clld will
 test against the floor's position.
 
+The Cursor x, and y velocitiy is the speed which the cursor is moving
+at, in either axies.
+
 Floor x, y, and z are the coordinates of the floor, which is used by
 clld as the reference position that will be tested against the cursor.
 
+The Floor width, and height is just like the Cursor's.
