What's the best way for naval units to not be able to go on land, other than making a ton of locations on the edges of the land and moving them back to the water when they get near? I want only a selected few air units to be unable to go on land, because there are also airplanes (meaning i will need specific conditions for the type of unit rather than having a location checked only to air). There will also be multiples of the same unit (centerview and move land unit to the spot beneath the air unit will not work). Is there a simple way to do this?

Uh, I know what you're getting at, but I don't see a simple solution. A friend and I were working on box triggers, if you want to look at that. It uses quite a bit of locations, though, and won't be a reasonable solution...

You can place burrowed units around the edges of land, and run a detection system of bringing a unit to a location running through the burrowed units.

Conditions:
Player 7 brings at least 1 burrowed unit to anywhere
Actions:
Move location labelled locationX on burrowed unit owned by player 7
Give 1 burrowed unit owned by player 7 at anywhere to player 8
Preserve Trigger

Conditions:
Player 7 brings at most 0 burrowed unit to anywhere
Actions:
Give all burrowed unit owned by player 8 at anywhere to player 7
Preserve Trigger

Conditions:
Current Player brings at least 1 "naval ship unit" to locationX
OR
Always
Actions:
Kill all "naval ship unit" for current player at locationX
Preserve Trigger


Note: I used "kill" because it's the easiest and the one that makes the most sense. Naval units would be destroyed if they crashed upon land.

Edit: Nude's post (below) wouldn't work (or would be very complex/have a delay) if you have a lot of units of the same type.

Constantly move a burrowed unit under the naval unit.
Now if you detect the burrowed unit underneath you know its illegally on land.

You might want to kill the unit, or use some kind of mobile grid (also using burrowed and air units) to order it back in the direction of water.

I agree with Roy, but instead, just use a centered location on your navel units and then when it detects the unit, it stops the location and you move back... like Ðrant did on his Labyrinthos map, but you cant use the high dirt and stuff for them

edit: you cant use more then 1 navel unit unless you make other locations and share with other players...

You could use the mobile grid, then try and move the zergling to all directions, if you hit a direction that the zergling cannot be moved to, order the wraith there, of course, that would cause problems if you can unplaceable terrain next to the shore, such as cliffs.

Yeah but i might use more than 1 of the same unit, and then that means i can't use mobile grids or center a location on the naval unit.

More than 1 for each player, or 1 per player? If it's more than 1 per player, you're going to have to use massive amounts of locations, or run through a bunch of zerglings, checking for air units, which would cause lag depending on how large your coasts are..

Uh, I didn't mention either of those two ideas. So... My idea would work?

And what's with these moving back ideas? If you're going for realism, ships would be completely destroyed if they try to keep a course straight through land.

The Great Yam had a concept going. You should PM/Contact him.

This.

You could make it so all the coastlines are high ground then make a location over the entire map and kill the specified units when they go to that location. That of course limits your coast choices, but should be a simple solution.

That isn't going to work on multi units, unless you put locations on all land terrain so when the air unit goes on it and it detects a burrowed unit, it kills it.

Actually, you could implement Nude's idea very easily. Just have the location that the burrowed unit moves to recycle.

The most seamless ship crash system can be implemented on the Snow tileset, which has two different Water elevations. Simply make a river using Water in the low elevation and then use a map editor that can edit by tile to use the shore tiles from the High Water elevation to replace the shore tiles near the regular Water. Create a location that covers the whole river that only applies to "High Air" and always kill any units in that location. If you would like this to also apply to a river in the High Water level, simply repeat the whole thing with Low and High reversed.

This is what I suggested, but my way works on all tilesets; while it is not quite so seamless, it does work

If you are willing to spend some time on it, you can use a coordinate grid to program in the tiles that the unit is not supposed to go to and move them back. IE, tile 56, 56 is part of the cliff wall, so you move it back to a water tile such as 55,56 or kill it.

Using NudeRaider's idea:

Locations are centered on the various "ships".
Triggers involve moving a burrowed zergling to the location in which the "ship" is located.
Normally, this is impossible, as zerglings cannot be on water (normally...)
Zergling gets detected in location, kill ship.

However, this may backfire, I haven't tested it myself, but it is possible that with usage of multiple ships:

Via hyper triggers, the location moves too quickly and either
A: Misses the ship death target
B: Kills some random ship

Following my method, when he has multiple ships of the same type per player then he needs some cycling system which constantly causes deselect. So this is really only an option for a computer player.

I have no idea how it may miss the target or kill random ships. It won't do it if you set it up properly.


If it just so happens that human players can control multiple shps of the same type then you will need to use the high/low elevation trick mentioned. If you have no other high elevation (like temple terrain) then this would be the method of choice, because you'd only need a single location.

I'm still not certain this would work on multiple units, if you center a location on a unit inside a high-air only location, and there's other units not on high ground, will it center on them?

No, it will only center on the units inside the location. Units with the wrong elevation are not inside the location.
