ObjectCreationUpgrade?

[Stygs 25]

Hi there,

 

I was trying to recreate the CnC Generals drone upgrades, but it seems ObjectCreationUpgrade doenst seem to work anymore - any suggestions what else I could use?

[Mjjstral 25]

Just a random idea: Use "ReplaceSelfUpgrade" module to get an equal object but which has an additional "SpawnUnitBehavior" or "SpawnBehavior" module that can give you the (slaved) drone. Give the drone a "SlavedUpdate" module (see here).

 

But wait maybe you can do it without ReplaceSelfUpgrade cause SpawnUnitBehavior has a LogicCommand entry so there might be a direct way. SpawnUnitBehavior was only used in BFME II and ROTWK but seems to be still in the C&C3 game.

Care to elaborate, can't remember the drones from generals all to well anymore...weren't they just a spy, repair and hellfire drone upgrade? Either im missing something or its jut using 3 object upgrades for each drones?

[Stygs 25]

Yeah, its just object upgrades - but ObjectCreationUpgrade was used to spawn them once the upgrade was purchased and I couldnt think of another simple way to trigger an OCL with an upgrade.

Ah ok, was thinking i was missing something, use the following then:

 

<SpawnBehavior
	id="ModuleTag_SpawnType1"
	SpawnNumberData="1"
	InitialBurst="1"
	SpawnReplaceDelayData="30s"
	SpawnedRequireSpawner="true"
        KillSpawnsOnCaptured="true"
	SpawnInsideBuilding="false"
	KillSpawnsOnDisabled="true">
	<Die
	     DeathTypes="ALL" />
	<SpawnTemplate>DroneType01</SpawnTemplate>
        <TriggerdBy>Upgrade_DroneType01</TriggerdBy>
</SpawnBehavior>

<SpawnBehavior
    id="ModuleTag_SpawnType2"
    SpawnNumberData="1"
    InitialBurst="1"
    SpawnReplaceDelayData="30s"
    SpawnedRequireSpawner="true"
KillSpawnsOnCaptured="true"
    SpawnInsideBuilding="false"
    KillSpawnsOnDisabled="true">
    <Die
     DeathTypes="ALL" />
    <SpawnTemplate>DroneType02</SpawnTemplate>
<TriggerdBy>Upgrade_DroneType02</TriggerdBy>
</SpawnBehavior>

<UpgradeTemplate id="Upgrade_DroneType01"
        Type="OBJECT"
        BuildCost="500"
        BuildTime="30.0s"
        SkirmishAIHeuristic="IGNORE">
        <GameDependency>
            <ForbiddenUpgrade>Upgrade_DroneType02</ForbiddenUpgrade>
         </GameDependency>
</UpgradeTemplate>

<UpgradeTemplate id="Upgrade_DroneType02"
        Type="OBJECT"
        BuildCost="500"
        BuildTime="30.0s"
        SkirmishAIHeuristic="IGNORE">
        <GameDependency>
            <ForbiddenUpgrade>Upgrade_DroneType01</ForbiddenUpgrade>
 </GameDependency>
</UpgradeTemplate>

 

Something along those lines should work.

This does mean it will replace drones free of charge.

Otherwise

Like Mjjstral said, you could look into the spawnunit module, but i havent worked with that module myself so dont know if it works. Also i don't think spawnunit behavior links the drone to its master by default. You might have the give it a spawn behavior anyway with a initial burst of 0 and no respawndata etc and a CanReclaimOrphans set to true. Maybe that could work

Is the issue that you want the ability to be able repurchase a drone if it gets destroyed? Because I cannot find a simple method to do that, none of the Generals or BFME spawn watching behaviours work (as you know).

[Stygs 25]

Supprisingly, that seems to work fine for me - the drone dies and I can buy a new one easily, just like in Generals.

 

But I kinda noticed that units in the game wont attack the drone on its own, so I guess I still have some work to do.

Interesting! I would like to see your method once you have finally ironed out your issues, that would be very useful!

The spawnunitbehavior module works then? Does it get slaved automaticly or did you do the reclaim orphans thing?

[Stygs 25]

Yes, it gets slaved automaticly - I am basicly using the GDI repair drone, exepct it is spawned by an unit and not a building. Works pretty much the way I wanted it right know.

 

 

For the unit:

			<SpawnBehavior
				id="ModuleTag_SpawnRepairDrones"
				SpawnNumberData="1"
				InitialBurst="1"
				SpawnedRequireSpawner="true"
				KillSpawnsOnCaptured="true"
				KillSpawnsOnDisabled="false">
				<Die
					DeathTypes="ALL" />
				<SpawnTemplate>ForgottenSapperRepairDrone</SpawnTemplate>
				<TriggeredBy>Upgrade_ForgottenHoundAmbulance</TriggeredBy>
			</SpawnBehavior>


For the drone (removes the upgrade on death):

			<UpgradeDie
				id="ModuleTag_DroneUpgrade"
				UpgradeId="Upgrade_ForgottenHoundAmbulance">
				<DieMuxData
					DeathTypes="ALL" />
			</UpgradeDie>

Are you using a simple upgrade purchase to spawn the unit with the <Spawnbehavior> or using the <spawnunitBehavior> with its corresponding logiccommand coding?

I am wondering because:

looking at your code snippet it would seem that either you use a player type upgrade and then loosing the drone would reset that upgrade for each 'master'unit like it (enless your master is a unique unit then it doesnt mather) or you use a object type upgrade and then normaly only the upgrade effecting the drone itself would be cleared on its death and not the masters upgrade? Enless the spawnbehavior or spawnunitbehavior links those 2 together someway?

[Stygs 25]

I am using an simple object upgrade and the Spawnbehavior, pretty much like in Generals, exept with Spawnbehavior instead of ObjectCreationUpgrade.

 

Theres even a comment in the Generals ini files refering to that:

 

From AmericaVehicleBattleDrone:

Behavior = UpgradeDie  ModuleTag_12
    ;This frees the object based upgrade for the producer object.
    DeathTypes = ALL
    UpgradeToRemove     = Upgrade_AmericaBattleDrone ModuleTag_13
  End

So yeah, UpgradeDie seems to be a special case and affect the unit and its producer.

That is interesting! thanks for the clarification.
