|
|
|
[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.]
