In this tutorial, we create an automatic door that opens when the player approaches, using basic Blueprint. Hello, welcome to Cerdas Inovasi Digital. In this tutorial, we learn basic Blueprint in Unreal Engine 5 by creating an automatic door. The door opens automatically when the player approaches, and closes again when the player moves away. Let's get started! Create a new project from the TetherPerson template, name it 'belajar Blueprint', then click Create. In the Content Browser, right-click in the empty area and select Blueprint Class. Select Actor as the parent class, since the door is an object placed in the level. Name it 'bp underscore pintu otomatis'. Double-click the Blueprint to open the Blueprint Editor. Click Add, select Cube, then name it 'pintu'. This cube will be the door panel. Change Location Z to 150, and Scale 0.2, 2, 3, so the shape is flat, wide 2 meters, and tall 3 meters. Select Default Scanner Root, then Add Box Collision. This invisible box will detect when the player enters the area in front of the door. Set Location Z to 100, and Box Extend 150, 200, 100, so the trigger area is wide enough on both sides of the door. Open the Event Grab tab, then remove the default node so the grab is clean. Select the Box Component, right-click in Grab, and select Add-on Component Begin Overlap. This event is triggered when something enters the box area. Also add On Component End Overlap, which is triggered when the player leaves the area. From Begin Overlap, drag the pin and add the Move Component 2 node. This node smoothly moves the component to a new position. Fill in Target Relative Location Z 400, meaning the door moves upward. Set Overtime to 1 second, then check Ease In and Ease Out for smooth movement. Connect End Overlap to the Return pin. Return to make the door return to its initial position, so the door closes again. Connect the door component to Grab, then connect it to Pin Component, so the node knows which component is being moved. Click Compile, Save, then close the Blueprint Editor. Drag the BP underscore automatic door from the content browser to the level, then set Location to 900, 0, 0, right in front of the initial player position. Click Save All to save everything. Press Play and walk forward. As soon as we approach, the door lifts up. After we pass and move away, the door lowers and closes again. Done. You have created an automatic door using Blueprint without writing any code. This Overlap and Move Component concept can be used for lifts, traps, and secret gates.
