Gecko JS

Use GeckoLib to create animatable block/item/armor by KubeJS

Simple Example

Startup script

StartupEvents.registry("block", event => { const rotating = RawAnimation.begin().thenLoop("rotating"); event.create("geckojs:example_block", "animatable") .box(1, 1, 1, 15, 15, 15, true) .animatableBlockEntity(blockEntity => { blockEntity.addController(state => state.setAndContinue(rotating)) }) .defaultGeoModel() })
