How to make a bridge that can be crossed underneath?

[sethmachine]

Hi,

How can we make it so a bridge can be crossed underneath it, e.g. if the bridge is spanning a gap in a canyon, the floor of the canyon down below should also be passable (since the units would go under the bridge).

WC3 bridges seem to defy this logic--bridges AFAIK are only walkable in one direction.

This is afaik not possible unless some real obscure complex solution is used. This is because you want to prevent units walking off of bridges, therefore requiring pathing blockers. And as we all know, pathing map is 2 dimensional so it will block everything at any height(assuming flying blocker)

You cant change that. But perhaps a workaround depending on what kind of map you are working on. Changing flying height, and unit classifications so they can't attack each other or w/e.

I've made something like this before, but as mentioned above it's very obscure.

My method was to have a set of "entry" regions, which will tell me if a unit is entering the bridge from above or below. If entering from above, the flying height will be increased so that the unit appears on top of the bridge. This cannot be done very smoothly, so the unit's height appears jump-y when entering/exiting.

Further complicating matters:

• Ground units will block each other on/under the bridge. You'll need to make a custom collision system.
• Melee units can attack each other on/under the bridge. Ranged units can attack through the bridge. You'll need to catch these orders. Not particularly hard, but it gets messy.
• You won't be able to click *on* the bridge. So if you want to move to a point on the bridge, the click goes "through" the bridge and the order is given to a spot underneath.
• Also as mentioned above, preventing units walking off the bridge in the wrong place. Pathing blockers isn't an option, so you'll need to use a looping SetUnitX/Y to prevent units walking off.

I used two waygates to transport units from one side to another. It is hard coded though and you cannot remove the #$%@king stupid effect.

You should be able to overwrite the effect using a blank .mdx.

AFAIR the waygate ability does not have a field for any effect.

 

[rulerofiron99]

It uses the Mass Teleport effect, so just overwrite that path using an import.

i.e. import a blank model file and set the path to Spells\Human\MassTeleport (or whatever it is)

And if he uses Mass Teleport as well, import a copy. I see.
