------------ Summary
The tutorial shows how to set up a button in Godot 4 that triggers a trap using signals. When the player enters the button’s Area2D, a custom signal is emitted that tells the crossbow trap to shoot an arrow. The lesson covers collision layers, adding scripts, preventing repeated triggers, and using set_deferred for safe property changes. It also explains how the crossbow and arrow work, including collision and damage detection. The tutorial ends with a short challenge for the viewer and links to sample code and an online demo.
