Doodler/Doodler.cpp@8:90e789413e0b, 2019-04-16 (annotated)

Committer:
el17m2h
Date:
Tue Apr 16 16:16:08 2019 +0000
Revision:
8:90e789413e0b
Parent:
7:0d9cee90ab0d
Child:
9:5e53bca2a4c2
Changed the update function in the doodler so that it will be reading the position and velocity and setting a new one every time it updates (so that I will not have to write it in the engine file).
