# How it works
|
||
|
|
## Format changes
|
||
|
|
### V1 to V2
|
||
|
|
The way enums are expressed for canvas shaders was changed,
|
||
|
|
now values are no longer constant numbers but instead booleans expressing whether they are selected.
|
||
|
|
|
||
|
|
## A quick tour
|
||
|
|
In ResourcePackManagerMixin, the conf.json will be parsed and saved to a map in the main class.
|
||
|
|
Now, whenever a resource is accessed, the mixins under conditions/ will check if a .rpo file exists
|
||
|
|
for the current resource and parse it if that is the case.
|
||
|
|
If a resource is "hidden", openFile will throw a FileNotFoundException and containsFile will return false,
|
||
|
|
essentialy preventing the game from even knowing the resource exists.
|
||
|
|
|
||
|
|
## Canvas integration
|
||
|
|
Grondag implemented an API into frex to allow RPO to supply a custom shader file which other may include,
|
||
|
|
the code is generated by each individual entry class.
