Hi Gabe, great video! I have 2 questions for you.
1) Do you know how to draw dashed lines using OpenGL? I need it for graphical implementations in my Game Engine.
2) At the end of the series will you show how to export games created with the Game Engine?
Thanks for the videos you make for us (The yellow cursor looks great!)

Can you do a video on how to make a particle system and have a emitter as a component that you can choose to be on all the time or to trigger? I’ve been playing around with it but can’t get it to work
