Can the "animation.frametime" property of .mcmeta be modified？

[yedaming12]

I've done some dynamic PNGS, but the minimum unit of refresh rate is 1tick, which is a very low frequency for me. I tried to modify them, but found it difficult. I don't know if you've ever thought about doing this. Maybe you can give me some guidance while I'm still trying to modify them.

Yes, you can modify the frametime property as specified in the animation format guide. Can you show what you've tried?

Keep in mind that the file extension needs to be .moremcmeta and not .mcmeta, and the property name is frametime and not frameTime.

I wanted to add enchantment to the ordinary blocks, you know if you put a lot of boxes there will be caused a significant drop in the computer frame rate(fps), so I didn't use the entity blocks,also for the entity blocks I know how to render them. But ordinary squares can only be dynamically textured, such as a 16*(16*1000) texture png.

Oh, by the way, I forgot to mention that I just need the visual effects of enchantment!

I think you'd be able to add the enchantment effect by using a Mixin to modify the VertexConsumer in the ModelBlockRenderer or BlockRenderDispatcher render methods to be a VertexMultiConsumer.Double. One of the parameters to the VertexMultiConsumer.Double constructor would be the original buffer, and the other would be a buffer for the enchantment glint render type.

Actually, I've always had a question. Ordinary blocks are not rendered every frame, so it is feasible to add a dynamic block in blockrender?

[soir20]

My understanding is that you'd need to use a block entity if you want quads to be dynamically added/removed, like if a block went from being un-enchanted to being enchanted. You could look at how the block breaking overlay is rendered in LevelRenderer#renderLevel for potential ideas if this isn't already implemented in Forge/Fabric libraries. I think GeckoLib adds some model animation capabilities, but I'm not familiar enough with it to say whether it would help you do what you want.

I don't think you'd have an issue with the enchantment texture updating. While the baked quads aren't regenerated every frame, textures should be OpenGL-bound and potentially updated every frame. That's how vanilla animated block textures work.

There's also some examples in the demo resource pack (see assets/minecraft/textures/entity/bat.png.moremcmeta).

Also, I'm going to convert this to a discussion thread since it's more of a question.
