Teleporters

I tried putting teleporters in my level but they don't work.

Did you title them correctly?
Sometimes I've found that typing in the title isn't enough and I'm required to try to enter it a few times. I've found hitting enter after typing it helps.

To make teleporters work you have to put titles on them, for example ta1 in one and ta2 on the other
If you want to make more pairs you put tb1/tb2, tc1/tc2 etc

Sometimes they don't work, it's random. I did title them
Anyways, I accidentally closed editor, and now spikes are permanently covering my map, so never mind

it has to start with "t"

If you do it correctly, there will be no randomness in your success

Be sure to label the entrance teleporter "ta1" and the exit "ta2." For the next pair, label them "tb1" and "tb2," respectively.

I named the first one "TA1" "TA2", didn't work.
I named the second one "tb1" "tb2", didn't work.
I renamed the second ones "Tb1" "Tb2", worked.
I made new ones "tc1" "tc2", didn't work, and caused above ones to stop working.
I renamed the one 2 lines above "tB1" "tB2" worked.
I renamed the one 2 lines above "Tc1" "Tc2", didn't work.
I renamed the very first one "ta1" "ta2", didn't work, but caused "Tc1" and "Tc2" to work.
I deleted "ta1" and "ta2", and replaced them with "Tc1" and "Tc2"
Then I was done, but it shouldn't be that hard...

Don't forget to press enter after naming a tele, in order to be sure that it got saved.

Also, they can not be very close to each other.
