Minecraft 2d inquiry...

HI

How can you make the player destory tilesets and place the like minecraft.
Also how could you make an invantry*

(sorry bad spelling)
 

I'm sure tuo has a demo that should help you. I think its called demo-miner

But is there anyone that know what you need to do to add placeable and destoryable tilesets

That's what jaybdemented is saying. A user on the forums named Tuo may have a demo on Stencylforge that does what you are looking for. Search for it or ask Tuo about it, as well as look at the demo.
