I have been working on this for a very long time! ------------------------------------------------------------ Have you ever wanted to test a 2D object''s aerodynamic ability? Have you ever wanted to test your 2D air-intakes? Probably not... But here you can test whatever you want! You must read everything here to understand! Sorry, it's very complicated! -----------------Instructions------------------------------ Default settings: 1. Click flag :P 2. Press Space to draw and object! (You can't erase yet, sorry) 3. Press the Up Arrow on your keyboard 4. Watch the airflow simulation! Keys: Space - Draw object Up arrow: Start simulation P - Pause A - Show/Hide variables D - A failed feature that I did not remove... Tweakables: Mode - Change to "old" (1) or "new" (2) mode. The old mode uses directions instead of X and Y variables! I wanted to keep the old version because I worked so long on it. The realistic value is (2)(Default: 2) Clonesize - Change the size of the green "circles" (Not recommended, I used it for debugging only) (Default: 100) Ghost - Change the transparency of the green "circles" Does not affect anything, but helped me debug and test stuff) (Default: 100) Drawlines - Change the lines... (0) Shows the airflow speed. (1) Shows the airflow direction. I recommend (1) because (0) is very buggy! (Default: 1) Starting y pos - The space between the circles. Click flag again to refresh! (Default: 14) And oh, if you are still reading, the bottom left number is the clone amount.
