I have found an easier way to float objects (immovable) on sandbox :D
and i am extremely sry for the lack of pics atm... my xbox refuses to connect to XBL but i will try to explain the best i can w/ words and get some up later
this could be used to easily float objects flush with block, doubles or w/e else u need something to be flush w/
NOTE: this is easiest to do in the Sky Bubble
Step 1: place walls/blocks w/e to hold the object in place
Step 2: hold the object against the holders firmly. now fly down thru the death barrier (yes, i did say the DEATH BARRIER, im sure most of u think im insane now, but i was building a map and accidentally found this when i flew too low.
Step 3: it should appear as tho it has fallen but there should be a spawn point there (the little teardrop) if there is not then this may only work in Local parties... (im sry for the lack of testing as i sed b4 my XBL isnt working...)
and if the teardrop is there for you start a new round and it should respawn floating in the correct spot :)
thx for all comments
some1 else testing this in an XBL party would help since my XBL is currently screwed up...
plz post to confirm or disprove this
Happy Forging
