View source for Configs/LocType

Loc means “Location” and represents all of the game objects in the world.

=== Structure ===
Regardless of the revision, the packing process has some basic rules.

# Loc names must be unique. They can have + symbols in the name.
# Configs are a purely text format with a custom parser. True/false values are written as yes/no.
# Opcodes are written in the order they're read in. This means the packing process is writing immediately as it parses, with a few exceptions for properties that are "collected" and written at the end (typically arrays or complex properties). If you decode to memory or a standard intermediate format, you will lose this information, not that it matters much for the end result. Only bother with this if you care to match the checksum exactly.

Because of #2 you'll also be able to see when they copy-paste lines and/or forget to remove old properties!<syntaxhighlight lang="ini">
[example]
name=Example
desc=This is an example
model=example
length=4
width=2
length=2
recol1s=5
recol1d=1234
</syntaxhighlight>

=== RS2 ===
Changes based on decompiling available clients. If a revision is off by a couple, it's because we were missing those clients or they were not auto-decompilable (yet) to narrow the revision down further. I'll refine this again later.

Names are an attempt to be authentic and correct, if you have any more information definitely reach out.

==== model Property ====
This property is used to render a specific model based on the shape. The shape to use comes from the map data and zone protocol.

This opcode is packed at the end of the config when we receive it in the cache.

===== Config =====
<syntaxhighlight lang="ini">
[example]
model=example
</syntaxhighlight>They only need to define this as a single <code>model=name</code>, the shape is derived by looking for suffixes on file names in their <code>src/models/</code> directory. The suffixes are not the shape numbers here but rather their map editor's hotkeys!

Scenario 1: a model <code>example_8.ob3</code> and they have <code>model=example</code> in their loc config. It sees <code>_8</code> and then knows to add shape=10.

Scenario 2: two models, <code>example_8.ob3</code> and <code>example_0.ob3</code> and they have <code>model=example</code> in their loc config. It sees both suffixes and knows to add shape=10 and shape=22 with those model IDs.

Scenario 3: two models, <code>example_8.ob3</code> and <code>example_0.ob3</code> again, but this time they have <code>model=example_0</code> in their loc config. It sees that it's a specific suffix and adds that grounddecor model using shape=10 instead. This is a very particular feature used to override the appearance of the standard centrepiece_straight shape.

==== name Property ====
This property is the visible tooltip name. Occasionally, the internal debug name can slip in here, but that isn't visible unless the loc is "active" (based on shape or explicitly defined).
