Need a trigger to replace certain type of buildings with another type.

[Mr.Cheese]

I'm not sure how to make a trigger for this one. It should be easy, but I am having difficulty.

When my map starts, depending on what race the player is, their towers will be their race's (for example, Undead will have ziggeraut, not 'cannon tower'.) There are many, many towers to replace.

I could make 100 small locations and specifically 'create' the towers there out of thin air. However, this would be time consuming to do, would clutter the map with locations, and I don't like it.

I have placed the towers all of a certain type and have tried to replace them all with another. But I haven't been able to figure out how to do this. Maybe it is possible in the flexibility of JASS, I have been going in circles in the GUI.

Another possibility I thought was starting everyone out with scout towers and just make a trigger 'upgrade' them to the way they are supposed to go.

Is there any way to replace a building with another without a specific location for that one building?

If all towers are the same, you could pick towers, ( picked unit is cannon tower ) , then ( if player is undead ) replace picked unit with zigurat, right ?

You could do something like this:

For each integer from 1 to (number of towers)
Pick a random (tower) from units matching conditions
-(conditions: unit type is equal to the type of tower you want replaced)
Save the position of picked unit to a variable
Destroy/Remove picked unit
Create a (new tower) at the position you saved as a variable
Clear the variable
---repeat---

If you are replacing ALL the towers of a certain type, then the "pick random" will work (if you have 6 towers and it picks a random one to replace 6 times, it will have to replace all of them). If not, you will have to pick each tower individually (by making each tower a unit variable or putting regions on each tower).

Theoretically, yes. What is tripping me up is the event to trigger it all in the first case.

For example, I have successfully been able to have a tower become another tower when it is blown up. However, I do not want to wait until it is 'blown up'. I want to replace it at the beginning due to race. So the event "Tower X is destroyed" and action "Create Tower Y at triggering unit location" wouldn't be useful, even though they work, since I cannot get the correct event (if one exists).

Anyone know if towers will cleanly upgrade to a very different tower? Perhaps I could trigger all the towers to upgrade to Tower X if race Human, Tower Y if race Undead, etc. I'll give that a try.

When the trigger where the race is chosen ends you could start the replace trigger. This shouldnt be a problem.

Did i understand you the right way? It is not the problem to replace the towers but when or how to start the trigger?

Why dont you make every tower on the map a basic tower that can be upgraded?

Event - Time Elapesed is 0.00 secs???

 

[Archangel_Tidusx]

Event - Time Elapesed is 0.00 secs???

How does that help? lol

 

[alpha 100 f]

It does not, there is no race chosen at that time

 

[Ham Ham]

How does that help? lol

What I got from his question is wich is the right event to add.

So, well. Elapsed Time is (Right Time after race is choosen) seconds?

 

[alpha 100 f]

This would be one posibility. or u use the action run trigger (checking conditions) at the end of the race choosing trigger. then there is no event needed

 

[Archangel_Tidusx]

It would leak. I would have a boolean condition for each player. Set it to true when each person selects a race and then run once all the active players have chosen a race.
The event would be the dialog button click, then an If, Then, Else function

Just do an event when the race is picked...
This could be anything depending on what your race selection system is.
If you start with a builder just do a unit enters map then pick all the towers owned by that player and do some condition to determine the race. Remeber to turn this trig off like .5 seconds after it is over so it doesnt work everytime a unit enters
