A program for the Tomb Raider Level Editor (TRLE) community.
Converts a Tomb Raider 4 .TR4 file to a TRLE project .prj file
aktrekker's TR2PRJ program doesn't get the geometry correct especially for some split sectors. This is an attempt to do a better job.
Advantages over TR2PRJ:
- More accurate geometry maybe
- TGA file alpha channel handled correctly
- Open Source
Disadvantages:
- Only for TR4 files
- No objects extracted
- No lights extracted
- No texturing info extracted (how aktrekker do this?)
- No triggers extracted
This is a Delphi 10.3.3 project.
Delphi 10 Community Edition is currently available for free. https://www.embarcadero.com/products/delphi/starter
The Vampyre Imaging Library is required for .TGA support. Download and change the Search Path in the Project Options setting to location of Imaging Library. This project assumes Imaging folder is in project directory. Use the version from the Mercurial repository since the latest release version does not compile with Delphi XE7. http://sourceforge.net/p/imaginglib/code/ci/default/tree/
Open .TR4 file. The room textures will be displayed.
Click Save As to save the .prj file and .tga file.
Only geometry and doors will be extracted to the .prj.
Opacity (the kind you cannot pass through) setting will also be extracted. But in some cases of Opacity between stacked rooms some sectors may be incorrectly set and display incorrectly. Clicking "Draw Doors" in NGLE will fix those sectors.
If you load a TR2PRJ project created from the same .TR4 then you have the option to import the textures and/or light info from that project.
To save the .tga file only, right click on the image and select Save TGA.
The geometry will not be perfect. Tall split sectors cannot be decompiled exactly for instance.
Also, sometimes NGLE will switch wall sectors next to doors to floor sectors. Need to convert back to wall sectors in NGLE in that case.
The .prj file will generate some error messages when loaded in the level editor.
A "Broken map at room 0" error will always appear. This will be auto repaired.
The cause of this error is known. It is required so the editor links all the rooms for moving in the 2D map display.
Texture importing will generate additional errors that NGLE also reports as fixed. These errors are logged in "error.log" in the NGLE folder.
TR42PRJ will create a text file with same name as the saved prj file which will describe the cause of some of these errors.
If aktrekker reading this, please consider releasing TR2PRJ source code.
