If you haven’t completed the previous tutorials yet, please complete them starting from Basic Usage.

This time, let’s use the Event node to wait for a trigger.
The details are as follows:

• Create a GameObject with a Logic Behavior component.
• Open and edit the graph in the Logic Editor window.
• Wait for a UI Button click with the Button.onClick event.

Create a new scene

If you have other scenes open, it will be confusing, so create a new scene.

• Select File > New Scene from the menu.
• In the New Scene window, select Basic (URP).
• Click the Create button

Creating a GameObject with Logic Behavior

Create a GameObject with a Logic Behavior component added to the Scene.

• Click the + button in Hierarchy.
• Select Logic Toolkit > Logic Behavior from the menu.
• Confirm the name by pressing Enter.

Opening the Logic Editor window

Graphs of Logic Behavior components are edited in the Logic Editor window.
If the window is not displayed, select a GameObject and click the “Edit” button in the Inspector to display it.

• Select the Logic Behavior object
• Click the Edit button on the Logic Behavior component in the Inspector window.

If the Logic Editor window is already displayed, the graph will switch in conjunction with selecting a GameObject in the Hierarchy window.

Create an Event node for Button.onClick

Create an Event node that listens for Button.onClick.

• Click on the graph view to give it focus
• Press the Space key to open the node creation menu
• Select the Members tab
• Enter Button.onClick in the search field
• Select onClick of UnityEngine.UI.Button from the list.
• Select Event from the node type selection menu
• Wait for compilation to finish
• Confirm the node name with the Enter key

About Event Nodes and EventComponents

We will explain the Event node and EventComponent that we created.

A vent node is a node that detects specific triggers and executes the connected node.
When an event trigger is detected, it executes the node connected to the execution port.
The type of event trigger to detect is defined in a node component called EventComponent.

This time, we use the member access function to create and use an EventComponent that waits for the invocation of an onClick event of type UnityEngine.UI.Button.
If you specify a Button component that waits for a click in the Target field, the node connected to the execution port of the Event node will be executed when that button is clicked.

The Start node we have used so far is also a type of Event node.

Creating a Button

Create a Button in the scene.

• Click the + button in Hierarchy.
• From the menu, select UI > Button – TextMeshPro
• When the TMP Importer window appears, click Import TMP Essentials.

Setting Button.onClick

Set the created Button

• Set the Target field to Button
  (You can set it by changing the reference type from Self to Value and then setting the object field, or by dragging and dropping a Button object from the Hierarchy into the Target field.)

Create a Debug.Log Action node

When the button is pressed, a message will be output to the console.

• Drag the output execute port of the Event node
• Drop it near the right side to open the node creation menu
• Select the Scripts tab
• Select Actions > Debug > Debug.Log from the list
• Confirm the node name by pressing Enter key.

Debug.Log Settings

CSet the string to be displayed on the console.

• Set the Message field to Clicked

Play and check

Once you’ve done this, your graph will look like this:

Press the play button to see how it works.

• When you click the button, confirm that Clicked is output to the Console.

If the Console window is not visible, select Window > General > Console from the menu to display it.
