Shield System

This is an independent shield system from SimpleRPG Core.

It provides a shield system similar to that of League of Legends and it has complete kubejs support.

for kubejs:

StartupEvents.registry("shield_system:shield_type", event => {
    //Create a simple unit shield that exists permanently
    event.create("kubejs_test_unit")
        .createSimpleUnitShield()

    //Create a simple shield group, where the unit shields of the shield group permanently exist
    event.create("kubejs_test_group")
        .createSimpleGroupShield()

    //Create a shield that lasts for 5 seconds and belongs to the shield group
    event.create("kubejs_test_time")
        .createTimeLimitedShield(20 * 5)

    //Create a shield that continuously decays within 5 seconds and belongs to the shield group
    event.create("kubejs_test_decay")
        .createDecayShield(20 * 5)

    //Next is the advanced section
    event.create("kubejs_custom_1")
        //Add shield provider
        .shieldFactory(
            //Use the unit shield constructor to provide kjs objects for the builder, making it easier to manage
            () => UnitShieldBuilder.of((initAmount) => new TestShield(initAmount))
                //tick
                .tick((kubeUnitShield, living) => {
                    kubeUnitShield.getKubeObject().tick(kubeUnitShield, living)
                })
                //save
                .save((kubeUnitShield, living) => {
                    kubeUnitShield.getKubeObject().save(kubeUnitShield, living)
                })
                //load
                .load((kubeUnitShield, living) => {
                    kubeUnitShield.getKubeObject().load(kubeUnitShield, living)
                })
                //Since it is a unit shield, a unit shield constructor should not be provided, but rather a unit shield should be provided directly. Therefore,. create (0)
                .build().create(0)
        )

    event.create("kubejs_cunstom_2")
        .shieldFactory(
            //Use shield group
            () => new GroupShield(
                   //Use the unit shield constructor to provide kjs objects for the builder, making it easier to manage
                UnitShieldBuilder.of((initAmount) => new TestShield(initAmount))
                    .tick((kubeUnitShield, living) => {
                        kubeUnitShield.getKubeObject().tick(kubeUnitShield, living)

                    //Since it is a shield group, there is no initial shield, so a unit shield constructor is provided here without the need for. create (0)
                    .build()
            )
        )

for API use
