Missile Hit Counter

[nebuluski]

Hi

 

I wonder if someone can help me, as I am trying to detect when a particular missile type hits a ship and add 1 to a counter (flag).

 

I have tried doing this with triggers using the "unit hits" condition, but need to filter this due to CIWS round strikes on the ships from the surrounding supporting ships (being registered) trying to knock down the incoming missiles!

 

Any help or pointers would be appreciated!

 

Cheers

You will need to use these two events : world.event.S_EVENT_SHOT and world.event.S_EVENT_SHOT and world.event.S_EVENT_HIT. You will create a function (or two, depending on what you need to achieve) like this:

function MaverickFired:onEvent(event)
if event.id == world.event.S_EVENT_SHOT then
... logic in here to get the fired weapon and increment fire counter with 1
end
end

function ShipHit:onEvent(event)
if event.id == world.event.S_EVENT_HIT then
... logic in here to get the unit being hit and increment hit counter with 1
end
end

world.addEventHandler(MaverickFired)
world.addEventHandler(ShipHit)

 

and don't forget to init these events by creating an empty object for both functions otherwise they will raise an error when you add the event to the world.

 

See what you get and then let me know, it should not be really difficult. Alternatively, you can use bomb in zone (make a zone around your ship which is just as big as the ship) and have a continous trigger to increment everytime a bomb is fired in that area.

Thanks I will look into this approach.

This is what I used to achieve what I needed:

 

do
ShipHit = {}
function ShipHit:onEvent(event)
if (event.id == world.event.S_EVENT_HIT) then
	env.info("Something has been hit")
	local wpnType = event.weapon:getTypeName()
	env.info("weapon used was:" .. wpnType)
	if wpnType == "KH-31A" then
		local tgtunit = event.target:getName()
		env.info("Target hit was:" .. tgtunit)
		if tgtunit == "Stennis" then
			local Stenniscounter = trigger.misc.getUserFlag('100')
			trigger.action.setUserFlag('100', Stenniscounter + 1)
		end
		if tgtunit == "Normandy" then
			local Normandycounter = trigger.misc.getUserFlag('101')
			trigger.action.setUserFlag('101', Normandycounter + 1)
		end
		if tgtunit == "FFG1" or "FFG2" or "FFG3" or "FFG4" then
			local FFGcounter = trigger.misc.getUserFlag('102')
			trigger.action.setUserFlag('102', FFGcounter + 1)
		end
	end
end
end

world.addEventHandler(ShipHit)

end;
