Trying to create 2x2 Unit with a custom corpse sprite.

[The Martian]

(Version of OpenXcom used is: "Nightlies 2017-11-02" Linux release.)



I've been trying to build a mod that introduces a 2x2 unit with a custom corpse sprite.
(I'll try tackling altering the 2x2's living sprites later.)

However I keep getting an error when I load the four sprites for the 2x2 corpse.

Here's the code I've added that appears to be creating the error.

Code: [Select]

extraSprites:
  - type: FLOOROB.PCK
    singleImage: true
    width: 32
    height: 40
    files:
      500: /Resources/Test_Tanks/FloorOb_TestTank_Corpse_1.png
      501: /Resources/Test_Tanks/FloorOb_TestTank_Corpse_2.png
      502: /Resources/Test_Tanks/FloorOb_TestTank_Corpse_3.png
      503: /Resources/Test_Tanks/FloorOb_TestTank_Corpse_4.png

I've made the new images load to the high values of "files: 500-503" so as not to overlap with anything used in the other mods I have installed. (Like the excellent Final Mod Pack.)

Code: [Select]

items:
  - type: TEST_TANK_CORPSE_1
    floorSprite: 500
    invWidth: 0
    invHeight: 0
    recover: false
  - type: TEST_TANK_CORPSE_2
    floorSprite: 501
    invWidth: 0
    invHeight: 0
    recover: false
  - type: TEST_TANK_CORPSE_3
    floorSprite: 502
    invWidth: 0
    invHeight: 0
    recover: false
  - type: TEST_TANK_CORPSE_4
    floorSprite: 503
    invWidth: 0
    invHeight: 0
    recover: false

Code: [Select]

    spriteSheet: NEWTANKS.PCK
    allowInv: false

In the openxcom.log file the following error was recorded:

Code: [Select]

[20-11-2017_22-54-34] [INFO] Loading extra resources from ruleset...
[20-11-2017_22-54-35] [INFO] requested file not found: /Resources/Test_Tanks/FloorOb_TestTank_Corpse_1.png

The mods file directory structure looks like this:

Code: [Select]

- openxcom
-- mods
--- Test_Tanks
---- Resources
----- Test_Tanks
------ FloorOb_TestTank_Corpse_1.png
------ FloorOb_TestTank_Corpse_2.png
------ FloorOb_TestTank_Corpse_3.png
------ FloorOb_TestTank_Corpse_4.png
---- Ruleset
----- *.rul (All the *.rul files belonging to this mod.)

As far as I can tell the four corpse *.png images are in the correct location.

I'd appreciate it if someone could point out what I'm doing wrong or link me to a tutorial on the subject.

I tried changing out the test FloorOb_TestTank_Corpse_#.png sprites for the ones used in the Final Mod Pack's MiB tank and a different error was produced.

It is not my plan to use the MiB sprites from the Final Mod Pack, but I figured that since they are already known to work I'd check if it was something specifically about the *.png that were being used in my customized test mod.

Here's the code as it looks now:

Code: [Select]

extraSprites:
  - type: FLOOROB.PCK
    singleImage: true
    width: 32
    height: 40
    files:
      500: /Resources/Test_Tanks/floorob_MIBTANK_CORPSE_1.gif
      501: /Resources/Test_Tanks/floorob_MIBTANK_CORPSE_2.gif
      502: /Resources/Test_Tanks/floorob_MIBTANK_CORPSE_3.gif
      503: /Resources/Test_Tanks/floorob_MIBTANK_CORPSE_4.gif
Here's the new error in the openxcom.log file:

Code: [Select]

[21-11-2017_23-52-01] [INFO] Loading extra resources from ruleset...
[21-11-2017_23-52-02] [INFO] requested file not found:
[21-11-2017_23-52-02] [ERROR] :SDL_RWFromFile(): No file or no mode specified

I've also been going over the UFOpaedia Ruleset Reference's extraSprite: section and Warboy1982's tutorial post on adding new custom graphics.

As far as I can tell all the necessary fields are present and have the correct variables assigned to them.

I also tried instead to make a directory into a sprite sheet as instructed by the UFOpaedia Ruleset Reference.


This is the attempted code:

Code: [Select]

extraSprites:
  - type: GIANTBUNNY.PCK
    singleImage: true
    width: 32
    height: 40
    files:
      0: /Resources/Test_Tanks/Corpse/
GIANTBUNNY.PCK was used in the tutorial example so I gave it a try. Using FLOOROB.PCK also produces the same error message.

Here is the openxcom.log error:

Code: [Select]

[22-11-2017_00-39-45] [INFO] Loading extra resources from ruleset...

so if you have this all well made there is no issue

Also:  When posting for help, the code as you have posted it is excellent.  Along with that, please upload a .zip of the whole mod.  That way resources can be compared with what is in the ruleset, etc.

Just looked at your code, and I think the issue is that you put a '/' before 'Resources.' Try replacing /Resources/Test_Tanks/filename.png with Resources/Test_Tanks/filename.png.

In this case I was modifying an existing mod as kind of a tutorial project so fortunately those variables already had been assigned. Thank you for posting your template having it will make creating a new 2x2 unit much easier.

I think the issue is that you put a '/' before 'Resources.' Try replacing /Resources/Test_Tanks/filename.png with Resources/Test_Tanks/filename.png.

Thank you for spotting that, the extra "/" does indeed appear to have been the problem. Everything is now working correctly when the aliens cause the tanks to stop working correctly. -_^

please upload a .zip of the whole mod.

Sorry about that. I was modifying someone else's mod as a training exercise and I wasn't sure about what the forum etiquette was for uploading a mod based on another's work.

Which I see now was redundant as the original author mentioned on the mods forum thread: "As always, feel free to use whatever for whatever."

So I'll upload it there in case anyone is curious.

Basically I was just modifying the Alloy Ground Tanks mod by CryptoCactus to use Hellrazor's Alloy Tank Corpse sprites. ^_^

Thanks for this topic! It helped me to finish my own corpses project.
