About this project
What does Phantasia add?
A scripting/viewer mod for a vast array of Tech/Magic mods to help make understanding of mechanics easier. As of now base mc, ars, and gregtech modern are the mods supported with more mods planned for later.
Phantasia was built when I tried to use Ponder outside of create and realized while Ponder is truly amazing it fails to have ease of use for developers. So Phantasia was designed from the ground up to have all of it's systems easily designable in game without having to know any code to use/make for it in modpacks.
Everything you would need to access as a player is accessible in game including a theme editor, emi tree breakdown of the machine you are viewing, multiple machine Scenes, per machine scripts, text focused guides, a keybind for directly opening Phantasia screens, and a lot more.
As a dev everything a player would actually see through Phantasia is through the ingame editors and systems. As an exception to this rule we have the configs for giving the manual on first join and the first join toast settings. You can also set the defaults for the settings that can be changed in the ingame settings gui.
The settings you can change ingame include:
- Camera mode: Default: Camera is locked till player manually unlocks.
- Camera sensitivity.
- Zoom speed.
- Tooltip settings: Jade, Jade+Tooltip, Tooltip by itself, Hotbar only, Hotbar+Tooltip.
- How long it takes to open a Phantasia screen by holding the tooltip (in ticks).
- If the scripts autoplay on open.
- If the baseplate for scripts is shown.
- A theme editor where you can change/make your own themes.
- Performance mode: Balanced (default), a mix of script load time/quality, Performance, a mode focused on the ultimate load speed even if the blocks take a bit of time before they show, Quality, a mode focused on the top quality (loads all blocks before showing the script).
Config file only settings include:
- If the Phantasia Manual is given to players on first join.
- If the welcome toast is shown to players on first join.
- How long the welcome toast stays if enabled.
