In this episode I go over how to code powerups into our Mario game. I talk about how to create the Mushroom and Fire powerups and how to code the Mushroom AI. I also go over how to use Box2D's disabling collision feature to disable specific collisions.

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!)
Hey thanks MEC Craft! I found this Stack Overflow question for dashed lines (stackoverflow.com/questions/5321226/help-to-draw-a-dashed-line-in-opengl) it uses a really old version of OpenGL, but I believe you might be able to apply those concepts to modern OpenGL. You could also implement it yourself where you draw a bunch of small quads that go in the direction of the line (maybe I'll do a small mini-series dedicated to drawing lines one day). And at the end of this series I didn't plan on exporting the game, however I might give a broad overview on how I exported my game so that you could replicate it :)
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
Hey Jörgen, that sounds like a cool video to do one day. I haven't done particle systems yet, but I plan on implementing one sometime in the future. Once I get around to it, I'll definitely make a video on it :)
Why doesn't obs catch yours?
I think there might be some wrong settings somewhere
Coz mine one shows as far as I know
Actually lemme check now
Hey Lioncat, it catches my mouse in regular windows, but when I move my mouse cursor over a text edit box it disappears for some reason. If you find something you should definitely let me know though, or you can just ping me in the Discord :)
