New to Modding OpenRA - Crash becuase of new unit

scorp · Post by **scorp** » Sat Mar 08, 2014 9:57 pm

Hi everybody

Pretty amazed about OpenRA, i tried my hands at modding it a bit. Now i followed some turorials to create a new unit

https://github.com/OpenRA/OpenRA/wiki/C ... a-new-unit

i added a .shp file for it, an Icon shp file as well as the yaml rules in vehicles.yaml

Thing is however, once i build the war factory and the tanks become avaialble for building, i click on the Tab in the buildings Options to try to select the new unit - the game freezes and then crashes.

I suspect there's an issue with the Icon/cameo, but i used a placeholder from an existing tank for that... so does anybdy know/remember this crash from his own early modding days?

thanks for any help

Read the log files https://github.com/OpenRA/OpenRA/wiki/F ... st-crashed to find out what you did wrong. You can also type `make test` on Linux to automatically check for YAML errors.

so it might be an issue with the unit's palette? does every unit require a palette and Palette index of its own or can i use the palette from an existing unit?

*edit

fyi i'm trying to use a unit that comes with the OpenRA install itself, ftnk.shp as found in conquer.mix.

hmm okay the new unit doesn't seem to render. First mistake was in rules, now the mistakes are in sequences. gonna try to figure this out. not easy for Starters

for some reason, renderunit: was missing from the rules file. Now the i added it, but the game fails to load the sprite

i added the .shp file that came with the .mix Archive in pretty much any thinkable Folder and placed ftnkicon.shp files as well... according to the tutorial, These two files should be in the bits Folder and referenced in rules and requences, right?

same problem, i can't even replace d2k harvester shp files to ra harvester shp files...

this problem is not happening in original RA2 game modification process.

scorp · Post by **scorp** » Tue Mar 11, 2014 9:54 pm

yeah. it appears both changes to the YAML files as well as the use of custom .shp's is very sensitive to Errors.

for example simply copy-pasting a property from one infantry unit to a vehicle unit also caused a Crash at Startup for me. So the yaml-reading code at game start seems to quit easily. Might be a design choice for Debugging purposes or something

i guess those copy-pasting mechanics shown in the walkthroughs/ modding tutorials don't apply for my Version. Simply rendering a different unit as the custom unit (as shown in tutorial) also crashed the game.

I dunno. Maybe i'll have to try future Versions. No idea $:\$

hmmm converting the .shp in xcc mixer seems to have ultimately fixed it and my unit works fine. Gonna have to make a proper cameo for it instead of a placeholder, though. also twaek and Balance the ftnk.

I also use xcc mixer, BUT:

Maybe I 'm doing something wrong?

Objective: To replace the view from the Ordos Construction Yard (if you can call it that) . SHP is taken from here : http://openra.ppmsite.com/d2k-complete-packages.zip

Changes that I brought :

1) I renamed the file conyardo.shp --> test.shp

2) placed test.shp in folder: mods \ d2k \ bits

3) then, in the file: mods \ d2k \ rules \ ordos.yaml , I added code:
------------------------------------------------------------
CONYARDO:
Inherits: ^CONYARD
RenderUnit:
Image: TEST
------------------------------------------------------------
Result: Game crashes during deployment mcv:

What is my mistake ?

are you able to post the modified section of yaml from your rules and sequences vehicles.yaml files? Also a copy of the SHP that you are trying to add? The fact that it crashes when you try to look at it narrows it down, probably to the icon SHP though.

You can't mix two incompatible render traits like RenderBuilding (inherited from ^CONYARD) and RenderUnit which is for mobile things. They need sprites for every direction (facings).

If RenderBuilding inherited from ^ CONYARD then why every House has a different view of the construction yard?

attached the SHP and modified section of yaml.

And I did not edit sequences vehicles.yaml

Having a similar problem here. I tried to modify the ra flame thrower to be used as a harkonnen flame thrower for d2k. I get this error message at start:

Ok seems like i can not use td shps for d2k. I tried TS shps and it worked but i am having a problem with the facing. My Chem Trooper walks in circles... and when i open the TS shp in OS shp builder there is a problem starting from frame 89. The TD shp version works fine in OS shp builder.

PS: attached the Chem trooper (still WIP though)

sequence yaml:

EDIT: Might there be a problem how the frames are arranged inside the shp?

The D2K sprites are ordered differently to TD/RA, which is why they use negative facings and define Transpose: true. If you are using TD shps, then you need to remove Transpose and use positive facings.

Thanks! It works now!
