|
[10:38][Fixing backward movement]
|

[12:02][Fixing divide by zero]
|
|
[14:20][Actually move the player]
|
|
[18:08][Description of partial wall penetration]
|
|
[19:00][Adding the remaining wall tests]
|
|
[23:08][New problem: walking through the top wall due to floating point precision loss]
|
|
[25:27][Implementing a temporary fix]
|
|
[29:15][Looking for another bug causing the character to stop early]
|
|
[30:06][Debugging an assertion failure]
|
|
[32:50][More collision bugs; time to write a better collision detection system!]
|
|
[33:38][Observing the problems with the current collision detection system]
|
|
[35:25][What we want from the new system]
|
|
[43:26][Q&A][:speech]
|
|
[43:53][Can you change the whiteboard colors?]
|
|
[46:33][Do you plan on getting into calculus to get better collision detection?]
|
|
[47:05][Do you think any need to prototype some features in some other language?]
|
|
[47:43][If we changed the resolution of the game, would it change the size of the objects?]
|
|
[48:25][Can you do collision detection based on if a bitmap and a pixel has alpha?]
|
|
[51:15][Is it interesting to have a tutorial on floating-point computations?]
|
|
[52:05][Why not use the old collision system and use the new one only if it finds a collision?]
|
|
[53:03][What about the tiles? Will they stay the same if you change resolution?]
|
|
[54:53][What is dynamic loading? I thought C code has to be compiled.]
