Upgrade units with triggers

[Xzere]

Hello, i wonder if there is a very simple solution to upgrade units for a TD with lots of levels.

So instead of making 10, 20 etc. Units in the object editor, are there a simple way to only need 1 unit which upgrades through triggers instead?

You can use Abilities, literal Upgrades, and functions that directly manipulate a Unit's stats:

• Set Variable CurrentLevel = CurrentLevel + 1
• Player - Set the current research level of Iron Forged Swords to CurrentLevel for Player 1 (Red)

You can find these under the Unit/Player categories in the Trigger Editor.

Would this affect only the targeted unit, or would this affect all of the units of the same type?

Upgrades would affect all units of the same type if applicable

You could add bonuses to unit using New Bonus [vJASS][LUA] (or modify item stats "manually" via triggers) or modify base-values "manually" too.
When I say "manually" I mean calling the appropriate natives yourself (I think most of them are available in GUI).

Upgrades are what you research from a building which takes resources/time. I'm sure you've played a ladder game before where you researched an Upgrade like Animal War Training from the Barracks which increased the Hit Points of your Knights/Gryphon Riders.

You can customize and create your own Upgrades inside of the Object Editor. Just remember that your Units will then need to be setup to USE these Upgrades which is done in the Object Editor as well. Each unit has an Upgrades Used field, I recommend looking at the Knight as this uses Animal War Training which shows you how to increase it's Hit Points.

When you research an Upgrade using the Action in my previous post it will skip the resource costs/time.
