Global Interaction Handler

This example will send a message whenever the player interacts with the view or the player inventory itself, anywhere.

@Override
public void onClick(SlotClickContext slotClick) {
    slotClick.getPlayer().sendMessage("Clicked on " + slotClick.getClickedSlot());
}

Click context can be canceled to prevent player interaction with an item.

@Override
public void onClick(SlotClickContext slotClick) {
    slotClick.setCancelled(true);
}

IF by default gives you an option for these cases of cancellation that it is quite common, so it is possible to set them in the configuration.

@Override
public void onInit(ViewConfigBuilder config) {
    config.cancelOnClick();
}

Item Interaction Handlers

Items have a series of options related to interaction treatment, it is possible to define them individually for each of them.

import me.devnatan.inventoryframework.View;

class CoolView extends View {

    @Override
    public void onFirstRender(RenderContext render) {
	render.firstSlot(new ItemStack(Material.DIAMOND))
	    .onClick(click -> click.getPlayer().sendMessage("Clicked on diamond"));
    }

}

Item click handlers can also be cancelled.

import me.devnatan.inventoryframework.View;

class CoolView extends View {

    @Override
    public void onFirstRender(RenderContext render) {
	render.firstSlot(new ItemStack(Material.DIAMOND)).cancelOnClick();
    }

}

Individual de-cancellation is also supported in cases where there is global de-cancellation but you don't want it to be cancelled for a specific item.

import me.devnatan.inventoryframework.View;

class CoolView extends View {

    @Override
    public void onInit(ViewConfigBuilder config) {
        // Cancels click anywhere
	config.cancelOnClick();
    }

    @Override
    public void onFirstRender(RenderContext render) {
        // Will de-cancel click for this specific item
	render.firstSlot(new ItemStack(Material.DIAMOND)).onClick(click -> click.setCancelled(false));
    }

}

Player Inventory Interactions

Interaction handlers are also called in interactions of the player's own inventory, it is possible to distinguish which inventory was clicked using isOnEntityContainer().

import me.devnatan.inventoryframework.View;

class CoolView extends View {

    @Override
    public void onClick(SlotClickContext slotClick) {
        if (slotClick.isOnEntityContainer()) {
            // clicked on player inventory (bottom)
        } else {
            // clicked on view inventory (top)
        }
    }

}
