Problem with registration of node.

[Andrey01]

I am developing cube_nodes mod and i want to add a chance to paint the nodes in different colors by right-clicking dyes. But i have a lot of nodes with various images and that`s why i need to register each node with every possible colors (for example, "node_A" needs to be registered with red, pink, brown, green, blue colors and so each node). Any other way that would do without registration of so huge amount of nodes?

If you are concerned about creating code for each node, you could store all of the supported colors together in an array and loop through that array, so you are writing the code only once. I don't know of any way to reduce the actual amount of registered nodes. However, you may be able to use meta data to add color overlays. I don't know anything about meta data yet, so I don't know if that is a viable possibility.

Ok, thanks for answer. If it would be possible to add meta data it would be just nice and i would not need to register so huge amount of painted nodes.

You can indeed create up to 256 different colored nodes with only one node definition. The trick behind this is using palettes. However, this feature is rather new and thus, not used much yet.

It seems so way doesn`t fit. Let me tell in more detail that i want to do: i want to register only node, it will look like here:



Then i want to create "node painter" that will paint those white nodes, as it imagines on the image above. It will contain a formspec where player puts a dye and this machine outputs already painted node in according color. But it will paint the node only at edges and distinguish image inside as letter, number, punctuation marks. Then to paint remaining unpainted parts of nodes player needs to take a dye and right-click it. It will paint to according color. It`s all. But suggested API by you allows only to paint a node in only color entirely. Is there anything other way?

I don't know about the actual node generation, but somehow use image overlays. For example, have the basic block, and overlay it with colors, and further overlay it with basic shapes, letters, punctuation, etc.
