Buildable Waygates

[MrFrichyBoy]

Hello i am working on my custom warcraft map. I want the players to be able to build "tunnels" (waygates). There are two types of Tunnels, Tunnel A and Tunnel B. I want each player to be able to build only one of each. Each Tunnel is linked to the other, ie Tunnel A is linked to Tunnel B. These tunnels can be destroyed, but can't be used by enemies, only by other players. I want the tunnels to be linked for each players Tunnels, basically player ones two tunnels are linked with each other, but not with the other tunnels of the other players. If anyone knows how to make these buildable waygates work, the help would be super beneficial!

I would also like to know if this is even a possible thing to do in WC3?

Line 3083: WaygateSetDestination and other functions in common.j API. Yes you can build and link them dynamically.

These tunnels can be destroyed, but can't be used by enemies

I don't think this is possible, but I don't know the mechanics.

Woah I haven’t heard of common.j API before, what exactly is that? Could you send me a tutorial on how to use that? I was hoping to be able to do this via triggers.

Does anyone if this is possible? I don’t want to waste my time with trying to figure something out that is impossible. Thank you in advance

sure it's possible to trigger.

something like this:

for limiting to one per player, you make a trigger that detects when a player orders to build one of these buildings. if he already has one (or is currently building one), you order a stop command to the builder in the same trigger, and show an error message to the player that they can only build one.

for building the buildings -

trigger a:

whenever a tunnel building is completed:

add it to a unit group for all these tunnels.
if the peropdic tunnel trigger is off, turn it on.

periodic tunnel trigger:

for each unit in the unit group:

periodically checks what units are in range x of it (however close you want to actiavate it). (also make the buildings walkable in the unit editor). for units in that range - filter for allied units. after that, check if there is an allied unit of the other tunnel type in the map. if so, send the filtered units there.

if the tummel group is empty, turn off the periodic (this) trigger.

Thank you for the response, I appreciate it alot! I was able to set up the system for allowing players to be able to only build one of each tunnel. Im not able to set up the periodic tunnel trigger, could you show me how to do that part? Could you send a screenshot of how that trigger would look? Thank in advance!

      • Else - Actions

obviously as opposed to the native waygates - the game's pathing will not recognize these and they will need to be targeted directly, and units will not use them by default as the shortest path.

added the demo map (I didn't bother with tooltips, just order the peasant to build a farm).

good luck!

Another way to make tunnels is moving predefined regions.

steps:

• make your tunnel unit with walkable path
• create two predefined regions into ur map: TunnelEntranceRegion and TunnelExitRegion
• put these regions on inaccessible terrain to prevent units entering if no tunnel is available.
• Make a Unit enters Rect trigger for TunnelEntranceRegion
• Move entering unit to TunnelExitRegion on Trigger actions
• Use event Unit finished building when your tunnel is completed, to move TunnelEntranceRegion to Finished building location.
• When the tunnel is destroyed, return the region to its initial location.

Run test and make a Unit walk into ur tunnel.

To make unit come back, create another two regions in reverse order and repeat the steps. Dont use same regions cuz it'll make a infinite loop.
