History of loaders in ATLauncher
Before June 2019, if you wanted to install Forge loader into your pack, you had to use a special tool on the ATLauncher admin panel. This also meant that when Forge updated, you had to also re run and do the work to get it working with your pack.
Forge for 1.13 changed the way they install and no longer was it just a bunch of static jar files that had to be loaded in order to get Forge to work, you now had to run an installer, which would then run some programs in order to generate jar files for mappings. Since this could no longer be done on the server side without hosting the output jars ourselves, we moved towards adding loader support within the ATLauncher client itself.
This means easier configuration of loaders for you, and easier for us to maintain and update as needed, as well as more support for loaders as new ones come out.
How to add loaders
Now into how to actually add loaders to your pack.
It's simple really, simply define a new loader definition for the mod loader you want, directly under the </pack> section of your xml.
You can add a Forge loader to your pack for any Minecraft version 1.6.1 and above.
Now once you know which version of Forge you want to use (https://files.minecraftforge.net/) simply define a loader like below:
<loader type="forge" version="26.0.5"/>
If, while in development for a new version or pack, you want to constantly use the latest (or recommended) version of Forge, you can do so like below:
<loader type="forge" latest="true"/>
<loader type="forge" recommended="true"/>
You can also allow the user to select the version of Forge that they want to use. To do this, simply specify the choose argument like:
<loader type="forge" choose="true"/>
Note that while this is fine for development, you probably will want to make sure you use a fixed version before publishing. But hey, that's completely up to you and the type of pack you're running.
You can add a Fabric loader to your pack for any Minecraft version 1.14 and above.
Now once you know which version of Fabric you want to use (https://fabricmc.net/use/) simply grab the loader version (the yarn/mappings/intermediary version doesn't matter), then define a loader like below:
<loader type="fabric" loader="0.4.8+build.154" />
Much like with Forge, if you want to constantly use the latest version (there is no recommended version for Fabric), you can do so like below:
<loader type="fabric" latest="true" />
Just like with Forge, you can also allow the user to select the loader version themselves:
<loader type="fabric" choose="true"/>
Again this is fine for development, but you may wish to use a fixed version for release.
<version> <pack> <version>1.0.0</version> <minecraft>1.14</minecraft> </pack> <loader type="fabric" loader="0.4.8+build.154" /> </version>
