Shallow water restricted to submarines

[Kam]

I use the Gnomish Submarine on my map and the AI knows not to let it submerge or surface in shallow water, but it can travel through shallow water if it submerges in deep water. Is there any way to fix this?

 

[Kam]

bump

 

[Panto]

How does the AI know that? I'm not familiar with the model you're using nor the game mechanic that you're attempting to work with.

 

[Mecheon]

The model is one of Xaran's. I'm thinking he wants to find a way to get a unit to go to a submerged/morphed form and only be able to go on deep water instead of being able to go to shallow water

 

[Panto]

The easiest way to do this would be to simply place regions in all your deep water, and when the submerge ability is used, pause the unit, check if it's within one of those regions, and if it isn't, order it to stop, and then unpause it.

 

[Kam]

I thought of that, but it might lag, and it might not work when multiple units are doing it. It would seem to me that if blizzard made it so you can submerge or surface in shallow water they would have a way to restrict access to it. Any ideas?

 

[Panto]

Blizzard didn't make any difference between shallow and deep water except that "foot" and "horse" movement can't move in deep water, to my knowledge. I'm not sure what you're basing your presumption off of.

As long as there are no Waits in your trigger (and there should be none), even if it's in GUI, it won't mess up which unit's triggering it. It will always finish the trigger its executing before starting the next.

Also, as long as you don't do something silly like an infinite loop, it certainly won't lag. You're talking about a VERY simple trigger.

 

[Kam]

OK since I wouldn't know how to do that, any help?

 

[Eusira]

Or go nuts with pathing and make the sub air-pathable and place blockers essentially everywhere, but would totally screw air movement over water.

 

[Kam]

Ug stupid blizzard half assing sea units. *grunbles

Seriously though, how would I restrict submerged units from going into shallow water?

 

[Panto]

The answer to your most recent version of the same question already exists in this thread. Take what has been posted and play with it a little while. Once you've got any kinds of results, come back.

 

[Kam]

Your respose was too use regions to check the use of the submerge ability. The game already prevents the use of submerge in shallow water. I am trying to make it so a submerged unit can't enter shallow water. I am atm trying to use regions to accomplish this.

 

[Eusira]

Well you could use more pathing ideas, or just improvise on submarine movement

 

[Kam]

I'm not having much luck with triggers, I can make the trigger move a unit out of the region if it enters, but that's not what I want.

 

[Panto]

Pseudocode:

Event
Unit enters Region
Action
Pause Unit
Order Unit to "stop"
Unpause Unit

 

[Kam]

That would work except that once it is stopped, its already in the region and thus it can continue. Is there a way I could make a custom pathing blocker that only blocks certain units?

 

[Eusira]

No, not really. Unless you create like a neutral hostile unit with locust to attack the subs and sink them on shoreline for that, or cause them to move backward

 

[Panto]

Are they ever supposed to exist as un-submerged units? If so, then you can order them to emerge instead of stop.

 

[Kam]

Omg Panto I luv you. Why the crap didn't I think of that? And when the unit leaves the region I could make it resubmerge, so the user doesn't have to worry about it.

 

[Kam]

Well I can't get it to work, I even tried to use rocks to block the subs, they work but then regular boats can't go there. Maybe there is a way to do this with JASS, I really need an answer to this.

 

[Eusira]

Ever just replace the unit with relative life and mana?

 

[Kam]

What do you mean?

I waa thinking that the game differs shallow water from deep water only in the sense that ground units cannot walk in deep water. I thought that maybe if I changed the movement type of the subs to foot, but then for some reason they arent able to move even when I set their movement height to 180 or higher. Any thoughts?

 

[Panto]

Movement height is almost entirely an "art" field; it has no effect on the unit's ability to move. Morever, it only makes an effect on Hover and Fly movement types.
Lastly, Foot won't be able to go in deep water at all, which is the one thing you do want them to do. Why would you use Foot?

What was wrong with triggering an unsubmerge?

 

[Kam]

Foot would make sense if the units were able to walk in it. You see if they could, then the submerged sub would be restricted by the sam things a ground unit would. (IE the shallow terrian wall would then stop the unit as it does above the ocean.) I can't find a trigger command that allows to force a unit use an ability, and I started to lay the regions but ended up using over 100 for a reletively small area.(I was following the coastline exactly.)

I really think there could be a way to do this with JASS, as the game pathing knows not to let ground units fall off the side of the cliff in shallow water. I could use regions, but it seems to sloppy. I would end up using about 600 regions, and that is simply too much.

no Blizzard made naga be able to submerge in deep but not un shallow remember

 

[Panto]

The game doesn't calculate based on the terrain. It creates a pathing map when you save your map, and makes all its decisions off of that. If a unit can't move in a certain kind of pathing, it can't walk onto it and can't be placed there. The underwater cliff doesn't make a difference. Try sloping your underwater cliffs and see if units can walk over them, then.

Pathing can be unbuildable, unwalkable, or unfly-able, or any combination of those three, or none.

If you hit P in your world editor, you can see the pathing map. Blue represents unbuildable, red unwalkable, and green unfly-able, if I remember right. Combinations of colors represent combinations of pathing. For example, purple is both unbuildable and unwalkable. White cannot be built on, walked through, or flown over.

I'd encourage you to not follow the edges of your shallow water exactly, in order to generalize and use less regions. It will almost certainly be the most efficient and reliable method to solve this.

Well back to work then. I still need help on the actual trigger though, perhaps an exampls could be written?
