[1:14:40][Q&A][:speech]
|
|
[1:16:05][Garlandobloom says hi.]
|
|
[1:16:18][Can you explain the motivation behind controlling the page granularity.]
|
|
[1:22:35][Is the memory arena for more temporary objects than we're storing in the game state directly?]
|
|
[1:25:30][Why not have smooth scrolling?]
|
|
[1:26:20][We already have the -Oi compiler flag set.]
|
|
[1:29:32][Does using the memory arena still allow you to hotload your code?]
|
|
[1:31:31][Will we be implementing our own trig functions?]
|
|
[1:32:00][Will there be enough memory to store the entire sparse tile map?]
|
|
[1:32:43][Why not just allocate a large 1D array?]
|
|
[1:35:40][You're using a lot of pointers here. (Rant)]
|
|
[1:39:33][Will the memory arena be aligning the assigned memory?]
|
|
[1:39:52][Don't forget to disable -O2 again.]
|
|
[1:40:05][Comment on calling sin/cos for x86]
|
|
[1:40:57][Why don't you use lookup tables for sin/cos (Rant)]
|
|
[1:42:42][How can you say you don't need to free up memory?]
|
|
[1:43:28][Is memory access slower than MOV?]
|
|
[1:44:45][Why are tiles used? What is the real benefit of tile mapping?]
