I had to set like 30-40ish canvas blocks to make a small one-room theater and I was annoyed having to set the brightness and url of every one individually, I can’t imagine making something bigger. Total support here for something to mass-set canvas item properties haha
Fittingly reviving this post on World Art Day (it’s 1am in Australia, it counts!)
I’d love to see this as an Equippable any player could use, assuming Canvases then have the option (off by default) to allow being painted.
Failing that, a special “Painting Cube” with the sole purpose of being painted would also be great, possibly even an Easel item if we’re really talking business??
Left Click would do a “Sploosh” kinda wet paint sound and paint in front of you,
Right Click would sent the Paintbrush flying in a dead-straight line to allow long range painting.
This is different to the one you originally described in your post, which would be much better suited as part of the Tower Glove for sure but having both of these would be kickass.
I honestly would prefer either of those suggestions, so yours and the original, just being their own item - Or at least, have them be as both separate items and part of the Tower Glove. Why? I mean yeah, having it in Tower Glove along with other tools would be convenient, but seriously, you would look so much cooler just having a paintbrush or bucket of paint in your hand.
