PLEASE: RMVX SHORT RANGE TEMEPORT NEEDED!

Use a parallel process for this.
- Use a region ID to denote the areas you can blink.
- Use a conditional branch to check if the correct button is pressed.
- If you're allowing class changes, check to see if each character is set to that particular class instead. If it's just based on one character, make the whole event conditional on their being in the party.
- within this branch put another conditional branch to check if you're on the right region ID. (Use the script part of the conditional branch - last page - and put this snippet in: $game_player.region_id==63
Change the '63' to the same region number you're using.
- When the branch is true, make a move event that changes the hero speed to highest, makes the graphic blank and two '1 step forward'. Then change the graphic back, move the speed to normal and make sure it's set to 'Skip if cannot move'.

You can add a battle animation before the move event, too, if you wish.

Use a 'Through Hero On/Off' before and after the step forward. It will allow you to phase over tiles. The thing is, make sure you set up your map with the regions so that they can't get stuck in walls by using the ability.

Is there Terrain IDs in VX? You would need to track the hero's coordinates in variables. You would also track the Terrain ID in a variable. You would use some code to find out what is under the hero and what is in front of the hero.

I only know how to do that that in 2k3.

No script needed, and no terrain tags needed. You'll need an invisible event, marked by default as Pass Through, on every map. To simplify things, it would be helpful if the event had the same ID on every map. Easiest way to do this is to always paste the event down in a new map before you do anything else; then it'll always be event #1.

Then you need a parallel process that detects when the player presses A.

Any time you detect that the player presses A:
- Move an invisible event to the hero's location
- Detect which direction the hero is facing
- Turn Through ON for the invisible event
- Have the event face that direction and move two tiles forward
- Record which way the event is facing in a variable
- Turn Through OFF for the invisible event
- Have the event face the player (check the box that says "ignore if movement is impossible")
- Record the new direction that the event is now facing in a second variable
- If the event is stuck inside a wall/ocean, it will have failed to turn around and the direction it's facing will be the same in both variables. This means you shouldn't allow the player to teleport forward to that spot. However, if the event landed on walkable ground, it will have successfully turned around to face the player, and the two variables will be different. So if the variables are different, this means the player can safely teleport to the spot where the event landed.

As a note, this will allow the player to cross ANY one-tile-wide barrier. That seems to be what you want, though. If it's not, you'll need to use terrain tags to also detect the edges of water, or else just put an event at every spot in the game that can be teleported across.
