Code for episode 14

[obiwac]

To note: this was originally intended to be episode 13. Now, this will be episode 14, and episode 13 will be about general code cleanup and optimization.

Includes:

• OBJ model loader (could possibly be split into a separate tutorial?). (Instead, there's currently a converter script to convert Bedrock models to MCPY block model files. I might change my mind on this again though...)
• A bunch of entities, defined in an entity descriptor file (data/entities.mcpy). They can be spawned by pressing P.
• An instanced rendering system for rendering entities. (In the end, the bottleneck is by far from computing physics & collisions for entities, not from draw calls. Also incompatible with animation model.)
• Specific mob shaders for lighting them correctly (may end up in a future episode).
• The ability to save/load entities.
• Extremely basic mob AI.
• Mob animations.
• Use correct textures lol mobs: Using wrong textures #98
• Sort out normals, because they're incorrect. See paturage: Was transforming normals completely wrong in lighting calculation NovAti0n/MOOdle#16

The different entities include the player, pigs, zombies, skeletons, creepers, spiders, sheep, giants, slimes, and cows.

Will merge when the episode comes out on my YouTube channel!

yay

Can you please add a menu and infinite worlds too?

[Atten007]

And maybe multiplayer?

Infinite worlds are quite trivial to do, the problem is rather with chunk generation performance. I don't know if menus will be covered by a tutorial per se, but the one on 2D interface elements will come soon (right after episode 13 on mobs).

And maybe multiplayer?

That's planned, but not for the moment ;)

how about a villager mob?

[happyleibniz]

maybe you can set a trading system

[obiwac]

yeah that would be fun, once a UI system is in place! maybe to be added in the community directory because that's a bit out of scope for the episodes.

Obiwac didn't add a bottom texture or smt is true :) i checked the texture folder

@obiwac i cannot spawn mobs, i tried to press p continuously

[obiwac]

hey, E is the key to press to spawn a mob, P doesn't do anything

Oh, because I see you write

@obiwac
I press E and it spawns zombies, creepers and skeletons. How can I spawn a cow or pig?

[obiwac]

you have to add them as new entity types

[minh6079]

@obiwac How to add new entity types?
