Fixed issue where the custom logo wasnt showing in the game

[jlcd]

Problem

Custom logos were visible in the shop and could be positioned correctly, but disappeared when vehicles were purchased and spawned in the game world. The game logs showed two critical errors:

• 'getChildAt': Argument 1 has wrong type. Expected: Int. Actual: Nil
• 'link': Argument 1 has wrong type. Expected: Int. Actual: Nil

Root Cause Analysis

1. Stream corruption: BuyVehicleData.lua line 108 incorrectly used streamWriteStream() instead of streamWriteString() for parent path data
2. Unsafe parent node traversal: Vehicle.lua attempted to parse parent paths without proper validation, leading to nil values being passed to getChildAt() and link()
3. Missing error handling: Failed logo attachments caused crashes instead of graceful degradation

Changes Made

src/shop/BuyVehicleData.lua

• Line 108: Fixed streamWriteStream(streamId, logo.parent or "0|") → streamWriteString(streamId, logo.parent or "0|")
  • This was corrupting parent path data during network transmission between shop and vehicle spawning

src/vehicles/Vehicle.lua

• Enhanced parent path parsing in setCustomLogoData():

  • Added validation for empty path segments
  • Added tonumber() result validation before calling getChildAt()
  • Added null checks for parent nodes during traversal
  • Added informative debug logging for troubleshooting

• Improved error handling:

  • Gracefully handle cases where parent nodes cannot be found
  • Properly clean up resources (delete unused nodes) on failure
  • Mark failed logos for removal instead of crashing
  • Continue processing remaining logos even if some fail

• Restructured control flow:

  • Moved logo processing logic inside proper conditional blocks
  • Eliminated unsafe goto usage
  • Ensured all code paths properly handle success/failure scenarios

Testing

These changes resolve the nil reference errors and ensure custom logos properly transfer from shop configuration to spawned vehicles. The mod now handles edge cases gracefully and provides useful debug information when issues occur.

Files Changed

• src/shop/BuyVehicleData.lua
• src/vehicles/Vehicle.lua
