From Starcraft 2
Below, you will find a complete list (undergoing editing) of all the Object Types that an Effect can be. These are listed alphabetically and as are found in the Data Editor. As this list becomes more populated, we will link valuable tutorials and examples to each of the Effects listed - allowing you to learn (by example) how they operate in game and in the editor.
This effect is used to put a Behavior object onto a Unit.
This tutorial here uses a Behavior and an ability similar to Stimpack to increase the Shield armor and attack-speeds of an Archon: Tutorial - Psionic Focus
Applies a force. Can be used to create pushing spells.
Used to give a damage value to a spell.
This Effect creates a Missile that is launched according to it's linked Mover object. The Field which specifies the type of missile (actor of the projectile) is the ***Ammo Unit*** field. Here you can simply specify what missile you would like to use, from those already in the game. Creating your own missile requires knowledge about Actors.
One of the many effects required to create a Missile spell.
For further examples and comparative studies, have a look at the Longbolt Missile weapon (Missile Turret), the Punisher Grenade weapon (Marauder) or the Phase Cannon weapon (Photon Cannon).
Units which fire multiple missiles per shot - such as the Missile Turret - utilize Create Persistent effects to do so.
This effect allows you to modify a unit in anyway that you like. You can change it's Armor, it's Shield Armor, it's Life, it's Shields or its Energy.
Since you cannot give absolute modification values through triggers (e.g. +50 HP), you need to do these kinds of tasks with this effect.
An example of the Modify Unit effect would be for potions in an RPG.
Search Area effects are used to apply effects to other units. The effect looks for specific units in an area and applies an effect to them. The area is defined by range and arc parameters.
A Set is essentially a group of effects. When you trigger the Set, it triggers all Effects contained within the set, or randomly triggers a preset number of effects from the set. An example of this in action would be the Marauder - Punisher Grenade weapon. When the missile hits a target, it triggers a Set. This set applies both the damage the target will take and the Slow Buff (Apply Behavior) - provided that the Concussive Grenade upgrade is researched.
Used for a teleport spell such as the Blink ability the Stalker has.
