Hi all,
I am attempting to create a Portal Gun item for my single player adventure map. The idea of the item is pretty much the same as the portal gun in Portal game series: User can point to a location, create a portal which connects to previously created portal like a Waygate. Only 2 portals ever exist at the same time, old one gets removed as new one is created. Not too complicated, eh?
Well, I have been struggling with really perplexing bugs with the trigger system and now I have to resort to asking you guys for help. If some puzzle-loving, good-hearted soul is interested, I’d appreciate any help. I've heavily commented on my triggers so it would be easier for you people to help me troubleshoot this.
Be warned, this is a long post. I’ve tried multiple things to fix my own issues, and I go through my thoughts to help you read my GUI code.
Basically I have a couple of variables for referencing the locations of the two portals. These locations get updated as the portals are moved: the new portal is set up at the point referenced by the variable. Later on as units attempt to move through the portals, the location variables are used to compare distances and to actually teleport the units. The main issue with this is that both of the variables seemingly reference MULTIPLE locations, even though I thought that would be impossible. The portals get created with no issues, and my debug messages confirm that the variable was changed. However, as I use another debug trigger to ping the map to show the location of the points, they are elsewhere, even though no trigger should have changed them or reset them (I’d say they are at map centre, but I have not confirmed this). The teleportation system also does not work.
If I don’t use the variables and instead just reference points via the GUI function “Location of unit”, the system just works. But then the code leaks point references and takes a lot more processing power. Is this even an issue in a single player map?
The test map also has started to crash occasionally as I attempt to use the portal gun to create a new portal, but I have no idea why. To me it seems that I have no infinite loops, and I should be far away still from any memory limits. Could the crashes maybe be related to using the test map feature of the map editor? That’d be easy to solve at least...
Here are the triggers. I’m using version 1.30 so I can still create and play custom campaigns. This is something I can not easily give up with my map, as the design involves moving from map to map…
This one just enables the entire system:
When the item is acquired:
This trigger is one of the most troublesome ones. I manage to make it work if I DON'T use variables to reference points (PG_Portal1Location and PG_Portal2Location) and instead just call "Position of unit Shimmering portal 0011/0012" every time. Debug messages confirm that the if-else structure functions correctly, and that the location variables DO MOVE around. However when I fire my debug trigger (found below later), it pings totally different locations.
I think I could make this entire trigger shorter and nicer looking, but first I'd just love to see it work at all, even though this approach is not the most efficient.
In the end I resorted to using two preplaced portals, which I hide before they get used and then just move those two around and play some animations. This did work as long as I did not use point variables, but referencing unit location repeatedly is inefficient and leaks points. There's also the issue of crashing due to unknown reasons.
The system works by adding any units that are ordered to move to either portal to a unit group, which is then a condition for teleport in the two later triggers where a unit gets close to a portal. This way a unit can hang around the portal or move close to the portal and not get teleported (like Waygates work). Units only get teleported if the player commands them to move through the portal. The triggers repeat the move order with a slight offset, as just asking a unit to follow the portal would not move it close enough.
I currently use multiple triggers instead of one for easier troubleshoot, even though currently I have to repeat a lot of myself in the code.
I could make the portal system more beautiful by adding effects/sounds and tweaking animation times etc. but honestly I think I should at least make it work first...
As you hopefully can see, I've tried multiple different approaches, and none of them gives me the behaviour I want, is stable AND does not leak. I'm open to any suggestions, although I must warn you that I need handholding with JASS. I only know GUI and Google-fu...
Map posted below, there are some test spells there too. But the problem can't be that I'm approaching the "script limit" or whatever-one-calls-that, can it?
I'm a very inexperienced scripter, and even though I could just leave the custom spells from my map, this Portal Gun item is integral to the design and I need it to work. I'll gladly answer any questions.
If someone actually wants to use my scripts, feel free. If you can get them to work...

Map posted below, there are some test spells there too. But the problem can't be that I'm approaching the "script limit" or whatever-one-calls-that, can it?
I'm a very inexperienced scripter, and even though I could just leave the custom spells from my map, this Portal Gun item is integral to the design and I need it to work. I'll gladly answer any questions.
If someone actually wants to use my scripts, feel free. If you can get them to work...
