well, it's not a secret that voxel games are looking familiar to LEGO, and not a first mod/resourcepack/etc that makes blocks/nodes look like LEGO, but still it's the first minetest mod that does something like that!
TIP: if you want to place node with studs on top of other node with studs, then you need to point accurately on center of that node (to avoid placing on studs). if you will try to place node while pointing on studs, it will just place it 2 nodes above (so it will be like node-air-node instead of node-node) or in place where you're standing.
you mean setting selection box? like, if it will be set to default 1x1 node size, problem will be fixed and studs will work just as decoration i guess
(cause... changing nodebox? it's just description of model that engine should draw, it replaces selectionbox and collisionbox with nodebox if these aren't defined, that's it)
btw, what's about moving this into a thread or issue?
Review is still valid, no need to convert the review into a thread or issue, you can however move the conversation there and submit a commit to the repository.
Anyhow, like MisterE said, this can be fixed by just comenting out line 121 of init.lua: "selection_box = node_box"
Only need to delete/comment that line and the problem is fixed.
Of course doing this has a couple side effects: you can no longer select the studs, thus you can no longer dig a node by pointing at those, and obviously studs won't be highlited either. Basically, you turn the mod into something 100% aesthetic.
