First make a save point and save it in your inventory add a protected brain on the top of it.
Then place a small dark matter piece above it and add the object that releases items every time you set it at on it and make it so that it shoots out poison gas directly at the save gate.
Next make another piece of dark matter to where you want to warp and put the same thing on it and at the same hight but make it spit out the save point you created.
Finally, make a button and place it in front of the 1st save point you made and attach it to the protected brain and the 2 things on the dark matter you put.
Set the thing on the 1st dark matter with poison gas at 0.5 comes out with 1 life time and 2nd with the save point with same stats time.
Set the button at 1 shot thoough.
This allows you to travel depending on the settings on the things shooting out the paint balls.
then save the object you made.
nex use the thing that shoots out what ever you set at a sertant time. set it at your rain that you made and then timing at 5 and life depends how high you made it.
for it to leek use 1 rain drop and do the same thing.
