World Scaling | Handmade Hero Episode Guide

2:43Recap our current situation

5:00Take a look in handmade_render_group.cpp

5:58Render bitmaps using the DrawRectangleSlowly function

7:18Call through the slow path?

8:44Check it out in-game, considering how unoptimised the code is

11:50Blackboard: Scaling

15:23Blackboard: Intermediate buffering

16:54Blackboard: The stupid way^α

17:28Temporarily set the arrow keys to move the camera up and down

22:18Reduce the ZFudge factor

23:14See that the positions are being scaled, and go ahead and scale the size

25:45Check out the scaling in-game and note a bug with the tree popping

27:03Give the ground chunks a ZOffset

28:21Blackboard: Preventing leaning

28:56Do a Basis push for the GroundBuffer

30:07We're close, but things scale counter to each other

31:41Turn off the ground chunks and the debug rectangles, for now

32:38Take a good look at what's happening in-game

34:42Scale around ScreenCenter

36:12Moment of realisation: The EntityBasis->Offset.xy is currently incorrect

38:09Blackboard: How that Offset currently works

38:42Multiply the Offset by the ZFudge

39:35Check it out in-game and turn the ground chunks back on

41:27Show some problems with alpha fading

45:43Blackboard: Render buffers

46:57Turn off the ground buffer rendering and turn on multiple world layers

48:00Tweak the ZFudge

48:51Turn the ground buffers off entirely

49:23Consider the weird notion of Y-displacement for Z

50:50Set GlobalAlpha to 0 and try turning off that Y-displacement

53:50We want Z-slices

58:17ifingerbangedurcat Slightly off topic but, can you quickly go over the concept behind MoveSpec? Why not have every entity have their own velocity/drag, etc. values instead? Just for organization?

1:00:54rsxole If I'm not mistaken, with your way of Z-scaling it's going to be hard to support large (in Z) structures such as tall walls that should be aligned across different Z levels, no? Imagine a multi story house or so
