repositories {
  maven {
  	url = 'https://maven.riftrealms.de/releases'
  }
  repositories {
        maven { url 'https://maven.blamejared.com' }
    }
}

}

API

The Ritual API allows modders to add their own item actions, conditions and events that prevent a ritual from starting. They are registered in the common initializer with the following formats:

Conditions

ItemConditionPredicate YOUR_CONDITION = RitualApi.registerItemCondition(new Identifier("YOUR_MOD_ID", "YOUR_CONDITION_ID"), (ingredient, player, pos) -> {
        ItemStack stack = //Get the item stack
        return new Pair<>(ingredient.test(stack), stack);//Test the stack with the ingredient and return it for possible decrementing
    });

The default conditions are

• ritual-thingy:mainhand checks the item in the player's main hand

Actions

ItemConditionPredicate YOUR_ACTION = RitualApi.registerItemAction(new Identifier("YOUR_MOD_ID", "YOUR_ACTION_ID"), (stack, player, pos) -> {
        //Execute the action
    });

The default actions are

• ritual-thingy:none to do nothing
• ritual-thingy:give to give the item to the player
• ritual-thingy:drop to drop it at the ritual block's position
• ritual-thingy:drop_offset to drop it one block above the ritual block (on top of it)

Ritual prevention

PreventRitualCallback.EVENT.register((player, world, hand, hitResult) -> {
            return false; //Return false if a ritual is not allowed to happen
        });
