Finishing the General Purpose Allocator — Handmade Hero — Episode Guide

0:21Recap and plan for today

1:46We will need to debug the changes from the past episode

3:41Simplifying some of yesterday's code

7:34Finishing the merging of the freed blocks

10:14Implementing MergeIfPossible

16:01Modifying AcquireAssetMemory to check if the asset we are loading fits inside the newly freed space

16:47We're good!

19:16Potential problem of this general-purpose allocator: The linked list could be too long to walk on each allocation

25:33Fixing an error in OpenNextFile: If the platform layer failed to allocate the file handle, that function would fail to report the error

35:48Working with asset files containing Unicode characters

38:01On the importance of not exposing the concept of filenames to the game code

40:26Making the code work properly with Unicode file names

42:28wchar_t

47:41Isolating the game code from the concept of file extensions

53:55@blah238 I asked a similar question yesterday, but I guess it wasn't clear. Have you thought about how the asset system could work with 3rd party mods? Say someone wants to make a mod that adds new graphics, sounds and/or game logic. How hard would it be to implement a mod loader, Steam Workshop support, etc?

59:32@ifingerbangedurcat On MergeIfPossible, when you pass the checks and do the merge, you add the size of the header plus the size, but on the line before that you check that the (size + header) matches, but the size should already include the header. Can you explain why that is?

1:03:46@kknewkles You know I'm the biggest fan of the series, but I suspect for complete newbies the current way you construct the game makes little sense. Consider this: you know how to make a game, so you methodically cross over a check-list of components you know by heart (mostly). What would probably be easier and more graphic for larvas to grasp is to make a little functional game(title screen, game loop, game over, start over, etc) and THEN iterate upon it. It's more visual and having a little game that evolves every day little by little keeps the maker motivated, as opposed to a pro that knows what the game should look like in the end
