Blink not up cliffs

how can u make it so blink has a nice range of 512 but u cant blink up a cliff or down a cliff

replies are greatly appreciated

By any normal means you can't. You can create a dummyspell which is still cast and takes mana from the unit but if you aren't moved (Up a cliff) you can just give the mana back.

However...

I have no idea how you should check if it's up or down a cliff. That's pretty much impossible.

I think there is an action to check for cliff height

Yea, you can check cliff height of teh casting position and the target position and cancel the spell if the target is up on a cliff. It'll be MUCH more difficult to prevent it from blinking up a cliff and back down the other side.

just check a number of points between the caster point and the target point with a distance of 128 between them.

Hmm, you're right, it wouldn't be quite as painful as I thought it would.

In addition, you could still make the spell work, but only to the last point that isn't on a different cliff-level. So, if a player tries to blink onto a cliff, the spell is cancelled by another order that orders the unit to blink to the last point before the clifflevel-change. That way, the spell isn't cancelled alltogether, it just blinks as far as it can.

nah.. that'd be a waste, what if theyre right next to the cliff trying to go up it? thats just a waste of mana.
