Making a mod for chocolate doom, "R_ProjectSprite: invalid sprite frame 29:0"?

[WorldMachine]

This is really bugging me, I primarily need to know what they mean by "29:0".

 

I'm using SLADE3 for my modding if anyone needs to know

 

I haven't done jack SHIT for chocolate doom so I need guidence

Can a mod move this to "WAD Editing", just noticed I posted this in "WAD Discussion", sorry :(

Sprite frame 29:0 is POSSA(1-8). Are you trying to use custom sprites?

[WorldMachine]

Yes

[WorldMachine]

Hey, how do you know 29:0 are the zombiemen sprites?

Read this old tutorial from Doomworld on inserting custom sprites into vanilla Doom or watch this video by Doomkid:

 

You may notice that both of these tutorials mention the use of Dehacked, since it can tell the vanilla Doom engine to display custom sprites with completely different sprite-names by replacing string names (via Dehacked). Chocolate Doom runs in the vanilla Doom engine logic so that's why it gave you an error, because of its limitations.

Try using -merge, instead of -file when loading your wad file. See if it works

I am using dehacked, to change sprites around but it won't launch

Ok

[WorldMachine]

Holy shit! -merge works wtf?

[JustAthel]

It works because Vanilla Doom actually CAN'T handle loading custom sprites normally! A lot of old mods back in the day would use DeuSF to merge the new assets with the Doom IWAD. That's essentially what -merge does for chocolate-doom.

Got it, thanks >w<
