Signing in for a 7-days trial of the Nintendo Online sure affected how I used my hobby time these last days. But nevertheless, I could do some homebrew coding, and it was for the level editor.You may recall that I'd like to introduce 'direct flags tiles' in the engine. The idea is to enable any combination of some very basic properties like "can be swum through", "can be climbed on" or "can be fallen through" within the level by dedicating 64 tile types where the 'type identifier' part is used as a direct set of flags for those properties.Yet, that's only efficient if you don't have to come with 64 custom editor art for them. And that was only possible with a few changes to my MetaFlags widget and the surrounding code:paint color for 'environment type' tiles on/off switches for those tiles in MetaFlagsauto-generate combined tiles for combined environment (e.g. CAN_SWIM + CAN_CLIMB)"auto-generation" works by painting the the 'pure' tile with the highest bit, then painting over the lower-priority bits. So if you swap the order of  all-blue CAN_SWIM and some-green CAN_CLIMB, you won't see that you can do both anymore.It's far from perfect, especially because I still have to override that for the tile that says "plain air here, sir". But I realised it was merely an optimization over the 'indirect' tiles, and premature optimization is the cause of so much bad things ...
