Rendering Items Like the Clock

[Draco18s]

I want to render an item in a similar manner to the clock or compass, which uses an animated texture, but is not animated on a per-frame basis, but rather on other events (e.g. time, like the clock).

 

The way vanilla does this is it uses a subclass of TextureAtlasSprite and inside that it manages the animation directly.

 

However, there does not be a way to register a TextureAtlasSprite in such a way that actually WORKS.

 

In theory, this should work:

 

	@ForgeSubscribe
public void registerTextures(TextureStitchEvent.Pre event) {
	event.map.setTextureEntry("modid:calendar", new TextureCalendar("modid:calendar"));
}

 

But it doesn't, as you can only register sprites for objects that don't already have one registered, and by the time this event is called, there's already an entry in the Hashmap for that string (which is the same as the item's texturename*).

 

"Wait," you say, "You're trying to load a texture entry before any entries have been registered (TextureStitchEvent.Pre) and you can't because there's already an entry!?"

 

Yup.

 

It happens to be blank, but it DOES exist in the hashmap.

TextureAtlasSprite{name='modid:calendar', frameCount=0, rotated=false, x=0, y=0, height=0, width=0, u0=0.0, u1=0.0, v0=0.0, v1=0.0}

 

The texture I'm using obviously doesn't have 0 frames and 0 height and width.

 

But none the less that entry prevents me from registering my own TextureAtlasSprite.

 

How the hell am I supposed to do this?

 

*Using a different string doesn't work, as the item's texture string is used as a lookup in the hashmap.  Changing the item's texture string later also doesn't work.

Couldn't you use a custom IItemRenderer and bind textures manually based on the calendar / time? Might be a pain in the ass, but it should work.

I have a custom compass in there, but you can always use your TextureCalendar class. Especially look at those files:

Item class: https://github.com/SanAndreasP/EnderStuffPlus/blob/master/java/sanandreasp/mods/EnderStuffPlus/item/ItemAvisCompass.java#L22

Event class: https://github.com/SanAndreasP/EnderStuffPlus/blob/master/java/sanandreasp/mods/EnderStuffPlus/client/registry/IconRegistry.java

Texture class (use your TextureCalendar for this one): https://github.com/SanAndreasP/EnderStuffPlus/blob/master/java/sanandreasp/mods/EnderStuffPlus/client/texture/TextureAvisCompass.java

Yes.  And that's why not.

Oh man, that  helps.  I'll take another stab at it today.

 

Yay!

Man, that was obtuse; don't think I'd have ever figured that out on my own.  Thanks.
