We don't take element suggestions from in-game. I actually didn't even know this suggestion existed until now. Which is basically the reason, we aren't going to notice a suggestion unless it is on the forums (where suggestions belong). I'm demoting this save now. This save would be a great helper for a forum-based suggestion though, to show how it would work.
Sadly, breaking the rules (I dont agree with them either, but rules are rules) is not the way to get the mods to make an element. Figure out the coding required to do it, write it up, and send that to them, or make a powdertoy mod for it, and they would have less work to do, making it more likely to be implemented. also, when coding, consider that tpt might just not be able to handle it. Mods have worked a long time with it, so they have good reasons to not use moving solids
Also, GLUE is on the wiki page 'Previously requested elements' and has already been rejected due to being similar to moving solids.
I really hope that this will be added :D
+Potbelly already in the forum.
Lots of boring crap that uses many element slots to accomplish what? Go make it in Lua and see how boring it is. There's nothing to do with it that you can't already do with current elements. Either go to the forums and make a /good/ written out suggestion (not a wishlist) or drop it.
Jacob has done it somewhat successfully in his mod and one could argue that pistons have done the same thing.
how to make Glue: PLST + ACID = GLUE so when GLUE is heated to 50C or pressure of over 8 then it is turning back to PLST.
