# [AI]Making an AI for Worm War map, need help with making AI avoid death obstacles

If anyone hasn't played Worm War before, it's a map where each player gets Worm(hero), there are tons of sheep and pigs in around the map. If a Worm passes through the sheep or pig, it gets a unit(Segment) that follows the Worm.

Anyway, a Worm dies if it bumps into another Worm or a Worm trail or a fire elemental.

Basically, I am trying to make an AI for the map and I want to make it so that the AI Worm tries to avoid anything that kills it.

Right now, I have a very simple trigger that orders the (AI) Worm to move a random point in the map area every few seconds, that's basically is it.

Now, what I want to do now is make it so that the worm tries to avoid anything that kills it, I made a couple of tries at this but am unsuccessful.

What I basically tried to do for the trigger to check for any "Death Obstacles", is I made periodic trigger that happens once every 0.5 seconds.

It sets a point to the Worm, then makes a Unit Group "Within 300 range" of the worm "matching" unit equals <Segment> or <Fire Elemental>(both which kills the worm when touched).

Then, it sets a second point <position of random unit of Unit Group>. Then it checks if "Distance between Point1 and Point 2 is less than or equal to 300", if it's true, it orders the unit to move another random location.

Now, in game, it doesn't seem to be working at all, it doesn't make the computer move a random location if there is a segment or fire elemental nearby.

Here's some example triggers I have:
(Note - Computer Player Groups = All players equal computer and ComputerUnitGroupArray is all worms owned by a computer, both these variables is set before the game start and they do work because my move trigger is based off of them and that trigger works)

• Example 1
• Events
• Time - Every 0.50 seconds of game time
• Conditions
• Actions
• Player Group - Pick every player in ComputerPlayerGroup and do (Actions)
• Loop - Actions
• Unit Group - Pick every unit in ComputerUnitGroupArray[(Player number of (Picked player))] and do (Actions)
• Loop - Actions
• Set ComputerCheckPoint[(Player number of (Owner of (Picked unit)))] = (Position of (Picked unit))
• Set ComputerCheckGroup[(Player number of (Owner of (Picked unit)))] = (Units within 300.00 of ComputerCheckPoint[(Player number of (Owner of (Picked unit)))] matching ((((Matching unit) is alive) Equal to True) and (((Unit-type of (Matching unit)) Equal to Segment) or ((Unit-type of (Matching unit)) Equal to Fire Element))))
• Set ComputerCheckPoint2[(Player number of (Owner of (Picked unit)))] = (Position of (Random unit from ComputerCheckGroup[(Player number of (Owner of (Picked unit)))]))
• If (All Conditions are True) then do (Then Actions) else do (Else Actions)
• If - Conditions
• (Distance between ComputerCheckPoint[(Player number of (Owner of (Picked unit)))] and ComputerCheckPoint2[(Player number of (Owner of (Picked unit)))]) Less than or equal to 300.00
• Then - Actions
• Custom script: call RemoveLocation(udg_ComputerRandomPointArray[GetConvertedPlayerId(GetOwningPlayer(GetEnumUnit()))])
• Set ComputerRandomPointArray[(Player number of (Owner of (Picked unit)))] = (Random point in Arena <gen>)
• Set ComputerChatSegmentInteger[(Player number of (Picked player))] = (Number of living Segment units owned by (Picked player))
• Unit - Order (Picked unit) to Move To ComputerRandomPointArray[(Player number of (Owner of (Picked unit)))]
• Custom script: call RemoveLocation(udg_ComputerRandomPointArray[GetConvertedPlayerId(GetOwningPlayer(GetTriggerUnit()))])
• Else - Actions
• Wait 0.10 seconds
• Custom script: call RemoveLocation(udg_ComputerRandomPointArray[GetConvertedPlayerId(GetOwningPlayer(GetEnumUnit()))])
• Custom script: call DestroyGroup(udg_ComputerCheckGroup[GetConvertedPlayerId(GetOwningPlayer(GetEnumUnit()))])
Note - The main difference between the above trigger and the bottom trigger is that the bottom trigger sets the location to the "Picked" unit in the unit group instead of a "Random Unit"

Does setting a point to "Picked" unit of a unit group function properly?

So, does anyone know a way for me to make a trigger that checks if there is a unit within 300 range of the Worm(that can kill it), and if it's true, then it moves another location away from the location.

A trigger which tries to help the AI worm not get killed?

Any help will be appreciated.
