I was thinking of going with Mystcraft Intra-Linking books, but the Blood magic idea sounds very appealing (hope it works).IC2 has teleporters that work only within dimensions and use a LOT of energy (depending on distance); RFTools has teleporters that run on RF, again with the energy consumed scaling with distance (up to a point, which is the energy they use for cross-dimensional teleports); Mystcraft has linking books and portals (although getting those to work within dimensions is tricky); and Blood Magic has teleposers that should do the trick as well. You'll need a redstone signal to trigger the teleposers, but a pressure plate should suffice for that. Also, they may or may not be able to transport entities (such as players) across dimensions; support for that has been iffy in the past and I don't know whether or not it works at the moment.
I think that's about it. Oh, there's the ender rail from EnderIO which uses a dimensional transciever to teleport minecarts (with their contents), if that's your thing.
It should definitely work within a dimension, which it sounds like is what you're trying to do. You might have to do some engineering to get it to actually teleport you when you step on the pressure plate (as it might get the signal to activate before you're actually within its area of effect), but if it doesn't just work, a bit of redstone logic or an upgraded teleposition focus should do the trick.I was thinking of going with Mystcraft Intra-Linking books, but the Blood magic idea sounds very appealing (hope it works).
What I've done is make the teleposers teleport a 3x3 area and placed a lever on one of them. Pressure plates will teleport and remain stuck in the activated position, so they can't be used. On one of the teleposers (doesn't matter which) I had to set up a little NOT gate system because otherwise you would quickly be teleported to the other teleposer and then back from where you left.It should definitely work within a dimension, which it sounds like is what you're trying to do.
