Fuel pod

Is there a problem with the fuelpod from cargo and wrecks oxp.?

I have scooped it several times and nothing happens. I do not get extra fuel nor do I have a fuel leak, I only get the message “fuelpod scooped”. I am wondering if this is related with the bug of awardFuel command in 1.70

Something seems to be going wrong in the script_actions of fuelpod1 and fuelpod2:

Code: Select all

<key>script_actions</key>
		<array>
			<string>set: local_wreck_credits [credits_number]</string>
			<string>awardCredits: 1</string>
			<string>subtract: local_wreck_credits [credits_number]</string>
			<string>awardCredits: -1</string>
			<dict>
				<key>conditions</key>
				<array>
					<string>local_wreck_credits lessthan 0</string>
				</array>
				<key>do</key>
				<array>
					<string>awardEquipment: EQ_FUEL</string>
					<string>setFuelLeak: 2.5</string>
					<string>consoleMessage6s: FuelPod Failure!</string>
				</array>
				<key>else</key>
				<array>
					<string>performScriptActionOnTarget: commsMessage: [last-words]</string>
				   <string>performScriptActionOnTarget: becomeExplosion</string>
				</array>
			</dict>
		</array>
I did some testing with the current SVN build and here are the results:
The problem comes from the subtract: local_wreck_credits [credit_number] line, which returns infinity. Some more investigation reveals that the mission_key static variable that contains the name of the script running contains (nil) when subtract is called. Most likely, other methods involving local variables that are handled in a similar manner will have issues like this. Since the same top lines repeat also for other items in cargo_wrecks.oxp, this might explain why no cargo-specific messages appear when these crates are scooped.

Yeah, local variables only work for world scripts (script.plist) in the legacy system. No such problem in JavaScript. :-)

Hmmm, someone should add wrecks.oxp to their TODO list! :D

They did work in Oolite 1.69. But that they worked was a bug itself. In 1.69 I could change local variables with a ship and read them out in the normal script. But when a variable is local to a certain script, than the ship should not be able to generate a local variable that is usable by an other script. In 1.70 this is corrected. In UPS I changed them to mission_variables. I thing Cargo_wreck should also change those "local_wreck_credits" into "mission_wreck_credits"

It's the same bug. It uses "awardFuel" that is not working in 1.70. changing in "addFuel" should do the trick. (Or wait until Oolite 1.71)

Hmm. I think it’d be possible for foo_actions to have their own temporary local variables (rather than “accidentally” sharing those of the last named script). Assuming it doesn’t lead to complications, that would probably be best for compatibility.

Edit: Yep, that was simple enough.

Poor A_H.
From what I know he did all the testings on 1.69

I have already changed it but the fuelpod still do not work right due to the local variables.
I wanted to implement this method to Dr Nill’s ore processor, test it and finally PM Dr nill and recommend it as a nice upgrade to ore processor (and also for the scripted cargo in oohaul).
Unfortunately I took as example the code from cargo_wrecks.oxp and not that from UPS. Imagine the horrible moments I had (given the fact that I am not very good at scripting) trying to understand what I did wrong.
:x :x

Actually, I would think that awardFuel had been fixed to work on script target on 1.70. Ark, try editing the script_actions for fuelpod in shipdata.plist to

Code: Select all

<key>script_actions</key>
		<array>
			<string>awardFuel: 1.0</string>
			<string>commsMessage: 1.0 LY Fuel Transfered!</string>
		</array>
for fuelpod1 and

Code: Select all

<key>script_actions</key>
		<array>
			<string>awardEquipment: EQ_FUEL</string>
			<string>setFuelLeak: 2.5</string>
			<string>commsMessage: FuelPod Failure!</string>
		</array>
for fuelpod2. You should be able to have fuel awarded or leaked, depending on what fuelpod you scoop and this should also work with NPC ships.

Not in the plain 1.70 version. And those starting checking lines are necessary. Without then any NPC ship scooping a pod would give the player fuel. Remember the OXP is not only is used on 1.70+ but has to work also on 1.65 and earlier.

Thanks A_C :D
I will try it.

I agree about the pre-1.70 part of your response. If this doesn't work on 1.65, then it is not possible to use the OXP as intended. However, the awardFuel does work on 1.70 and other craft scooping fuel pods do not create leaks or award fuel to player. I run a small test with vanilla 1.70. Hyperspaced, and had a script generate some fuel pods and add a scavenger craft. Here is part of the log:

The first part of the entity dump is the scavenger at initial state. The second dump is after it had scooped a pod. You will see that its fuel has dropped to 0, as expected, without me (the player) experiencing any leak. But I did get a leak after scooping one of these pods myself. So, setFuelLeak works as intended. And below is the check for awardFuel itself:

See how the Llama is going from 0 fuel to 10, after it has scooped up a green fuelpod.

Edit: You can ignore the 1.70.1 mentioned in the script version running. It is actually a 1.70 executable that is being used.
Edit 2: Added the test for awardFuel itself.

I am probably confusing things. "awardFuel" didn't work in 1.70's AI scripting for fuelPod.oxp. I just assumed it didn't work for ships at all.

There are only a few commands that are explicitly excluded to work in ship scripts:

Code: Select all

awardCredits:
awardShipKills:
awardEquipment:
removeEquipment:
awardCargo:
removeAllCargo
The checking was done to differentiate for player/npc. Probably it was not necessary with the fuel pods. But is was necessary to use in combination with consoleMessages. Without this check you got those messages when a NPC ship shooped them.And console messages are better in this case as this means an internal generated message from the ships console as commsMessages are messages that are broadcasted by external objects.

Changing the word "local" into "mission" in those ships will also work and then everything works as intended. From version 1.63 onwards. (Introduction of the consoleMessage)

The problem with the FuelPod(Tank).oxp is that scriptActionOnTarget is not setting script target correctly with 1.70 (fixed already for next release). This may lead one to think that awardFuel is not working, when in fact the problem is somewhere else with that OXP, so I can see how confusion can be created.

As for the consoleMessage issue and the check for player / NPC, you are absolutely correct. I am indeed getting console messages when NPCs scoop stuff, when obviously this is not intended. So the local_* to mission_* change is indeed the recommended way to go about it here.

Thank you all for figuring this out, I'll keep lurking in the background and let you do all the hard work.
I'm loathe to fix stuff if it gets re-fixed again next reslease. :p
