| One of several [[Level Files]] located in a Mission's level folder, the '''NPL file''' is the compiled version of the [[NRN file]] (more specifically the [[NRM file]]), which controls all the [[Programming Mission Objectives|mission objectives]] for a level. The NPL file is not easily human-readable, and can only be read using a [[Hex-Editing Program]]. The game processes a level's mission objectives from this file, rather than the NRN file, and must be edited in order to make changes to the level.

| ==Description of Script Format==
| | [[Category:File formats in LEGO Rock Raiders for Windows]] |
| | |
| All script from the NRN file is compiled into four bytes (two little-endian 16-bit words) for each scripted number, parameter/function, and symbol.
| |
| | |
| Numbers end in <code>00 00</code>, [[Symbols]] end in <code>01 00</code>, and [[Parameters]] end in <code>02 00</code>. Certain [[Special Parameters]] also end in <code>04 00</code> and <code>08 00</code>. The first 16-bit word in each pair indicates the number, or the number that a symbol or parameter has been given. For example, the number 4 is <code>04 00 00 00</code>. Parameter #13, which is <code>GetCrystalsCurrentlyStored</code>, is <code>0D 00 02 00</code>. Symbol #5, which is the ">" symbol, is <code>05 00 01 00</code>.
| |
| | |
| Putting them altogether <code>GetCrystalsCurrentlyStored > 4</code> becomes <code>0D 00 02 00 05 00 01 00 04 00 00 00</code>.
| |
| | |
| This compiled code can be rather confusing at first, but once you figure out the patterns, it's as easy as searching for a string and changing it.
