Gate trigger

[Rayman]

Is it possible to make a trigger that will repeatedly force enemy units to attack the gate if gate is closed and to attack units behind the gate if the gate is open/destroyed?

 

[Boris_Spider]

It is. I don't have access to WE right now but it'll go along the lines of "every 2 seconds pick every unit in region and belonging to <attacking player>" (where the region contains the gates) and "order picked unit to attack gate".

I assume run the trigger every 2 seconds because the AI is likely to focus the units back on the ones behind the gate if they get attacked.

Alternatively you can make the gate a unit with a very small attack (AI will ignore it otherwise) and replace it with a destroyed gate doodad when it dies, via trigger.

order the unit to attack-move to a location. It'll attack anything it sees on its way. (not sure if it works on gates though)

If that doesn't work go with Boris's solution.

Theory #1 " Gate is a destructible " :

With a periodic event , or any event of your choice, check if the destructible 'Gate' is alive, if yes, pick every unit far from the gate X radius ( for example 500 ) then order it to attack. If the gate is destroyed, either do : 1- Pick every unit from 500 radius from the gate and order it to attack-move behind the gate, OR , create a region and order them to move to it, there are many solutions for this.

Theory #2 ' Gate is a unit ':

Just Order your units to attack-move behind the gate with one of the ways stated above ( using region point or polar offset ) , they will automatically attack the gate 'til they reach units behind it.

Example for polar offset :

• Set Beyond_The_Gate_Point = ( (Position of destructible 'Gate') offset by 600 towards (Gate Facing - 180))
• Unit Group - Pick every unit in Enemies_Group and do multiple actions
  • Loop - Actions
    • Unit - Issue order unit to attack-move to Beyond_The_Gate_Point

The AI will not auto-target gates, since they are neutral-passive non-units. I've never seen the AI destroy non-tree destructibles.

If the gate is a unit, it must have an attack for the AI to consider it to be worth killing unless no other enemy units are within the acquisition range.

Is the gate consider as destroyed when it is open?

Is the gate consider as destroyed when it is open?

yes. but if you destroy by hand it will play death anim not open
only by trigger u can play an "open gate" animation

He actually means Units behind the gate, he wasn't sure about the gate also

I didn't know you use AI, you had better add a very low attack ( 1 - 1 ) with range 1 ... It would not affect...

Is the gate consider as destroyed when it is open?

Not sure about this, afaik not.

You can open it by a trigger and add boolean that it's open, and instead of checking if it's dead, check if the boolean is correct. Like this:

• Animation - Play Gate 0001 Open Animation
• Set Gate_Is_Open = True

Then before ordering the AI to attack-move to the beyond-gate-location, check if this boolean is true...

 

[Lender]

Again, opened gates are considered dead , that is why u can walk through

I didn't know you use AI, you had better add a very low attack ( 1 - 1 ) with range 1 ... It would not affect...

make the bridge as a unit (neutral hostile) and set its priority to 20 (its the max)

then AI will target it first

however that means if there is a huge fight and there is one gate then AI will rush on it

He wants to make sure the gate is dead before attacking units behind the gate. Unless he has a visibility modifier in place, the units will attempt to kill whatever is attacking them. Destructibles don't get targeted as something to kill unless you specifically order them destroyed.

The AI control also dictates what un-microed player units do too. The 'call for help when attacked' will draw in all units that are standing around in the vicinity. Units with orders will ignore this. If the units are controlled by an AI players, you'll need to repeatedly tell them to attack the gate unless it is a unit with an attack. If it has no attack & no enemy units in the aquisition range are present - then the AI will target the defenseless unit.
