FOSS gamedev and creative worlds

My text api/signs3 mod is nearly done. The only hitch is you have to restart the game for the new textures to take effect, which doesn't cut it for me.

Combine can sortof create a new texture while the game is running, so long as youre combining textures that were loaded at startup, so same problem, my texs are being generated while the game is running.

Is there anything in the API that allows for the dynamic loading of textures, or am i gonna have to start looking to patching the engine? (if thats possible)

Can you load in a dummy image and then replace that image in game? You may have to write over the image cache.

the engine reads all the textures once at startup and that's it, no facilities to introduce new textures while it's running... which sucks cuz i can generate textures with text from within the game, i just can't use them until i restart. :(

Isn't there something in jin-xi's painting mod that generates new images?

This mod creates a object that contains the pixels. It doesnt create textures.

early versions used entities for single pixels, now it does indeed generate textures, see tile.cpp
textures on entities can be switched with set_properties. so there is a node for the "canvas", and on it an entity to switch textures.

Painting mods' no help either, uses "[combine:" which means its textures already exist at startup.

I can't use combine, since the texture doesn't exist until text2png() is called. My way has the added advantage of being able to chose font face, size and color, though as it stands the sign only shows up on restart. :/

simple white on black sign in verdana:

Still stuck on this.

Entities can dynamically change Textures.
