Reduced cost for tower upgrade

[UreDe4D]

So, i just got back to wc3 mapping after a looong break and i seem to have forgotten everything.

Simple Problem, i have x towers
lvl1 - 10 gold
lvl2 - 100 gold
lvl3 - 1000 gold
....


My worker can build all of them for the listed price. I also want them to be upgradable but for the price difference.

so lvl1 upgrades to lvl2 for 90 gold, lvl2 upgrades to lvl3 for 900 gold etc. I know it was something fairly easy but after googling for 30 mins i couldn't find it.

Help pls

I think you need to have 2 towers for each upgrade then.
lvl 1 tower - 10 gold cost to build
lvl 2 tower(1) - 100 gold cost to build
lvl 2 tower(2) - 90 gold cost to upgrade (not in the build list of your worker)
lvl 3 tower(1) - 1000 gold cost to build
lvl 3 tower(2) - 900 gold cost to upgrade (not in the build list of your worker)

yeah i have already thought of that too, but i was almost 100% sure there was a better way to do that.

Unfortunately, no. You'll have to do some sort of workaround to force a dynamic construction cost like that. The charge gold and lumber ability probably won't be your solution either, since it doesn't work with levels.

If a structure is upgraded, refund the gold difference using triggers. Sure the player will still need 1000 gold to start level 3, however they will be refunded 100 gold as they already own a level 2. Not ideal but better than nothing.

On an off topic note StarCraft II does exactly what you want with its unit morphs, keeping track of the total unit cost and only charging the difference.

ok, never mind, i'll use another way

share your solution please, this might become important for future researchers

I'm using a trigger option

• Events
  • Unit - A Unit is issued an order without target
• Conditions
  • issued order not equal to stop
  • ((Triggering unit) is a building) equal to True
• Actions
  • Player - Add (Point-value of (Triggering unit)) to (Owner of (Triggering unit)) current gold

So far i haven't found a way to exploit it, so i'll stick with it for now, if my towers get more abilitys later i may have to tweak the conditions a little.

Not at home atm
but I remember testing something about "use relative costs for upgrades" or something similar in gameplay costants (don't know how it is called in english)
I remember having it change upgrade costs in some way when I was testing it

will try again later

@Arrr thanks man i found it, i knew it was something fairly easy. (it's in the Gameplay section and you have to turn it to "false") can't tell you the english name either, but it was accurate enough for me to find the german one
