- 1. Events in Godot🎉 • Events connect nodes. • They are used for communication. • Events make games interactive. • They simplify node interactions.
- 2. What are Events?⚡ • Events are triggered by input or system. • They are handled by signals. • They simplify code structure. • They improve readability.
- 3. Types of Events •Input events capture user actions. • Built-in signals trigger automatically. • Custom signals are user-defined. • They cover most interactions.
- 4. Node Tree Flow🌳 • Events propagate through the scene tree. • They can be caught at multiple levels. • Handled by _input or _unhandled_input. • UI nodes use _gui_input.
- 5. InputEvent Example • Checkfor key press. • Check for mouse click. • Check for touch input. • Handle actions in _input.
- 6. Custom Signals • Definea signal in script. • Emit with emit_signal(). • Connect with connect() method. • They decouple node logic.
- 7. Event Bus Pattern •Use singleton for global events. • Centralizes communication. • Avoids tight coupling. • Keeps nodes organized.
- 8. One-Time Events • Useflags to avoid repetition. • Good for cutscenes. • Ensures unique triggers. • Simplifies gameplay flow.
- 9. Input + SignalExample • Player jumps on key press. • Signal triggers animation. • Animation plays once. • Node stays decoupled.
- 10. UI Events • Use_gui_input for buttons. • Detect clicks on UI. • Prevent event propagation. • Useful for menus.
- 11. Unhandled Input • Use_unhandled_input method. • Catches unprocessed events. • Allows fallback logic. • Keeps input safe.
- 12. Best Practices • Namesignals clearly. • Avoid too many signals. • Document signal purpose. • Test thoroughly.
- 13. Debugging 🐞 • Checksignal connections. • Print to console for debug. • Use debugger tool. • Fix missing connections.
- 14. Video Example • WatchGodot Signals tutorial. • Shows signals in practice. • Demonstrates node linking. • Helps beginners learn.
- 15. Summary ❓ • Events= interactivity. • Signals = connections. • Custom signals add flexibility. • Best practice keeps code clean.
- 16. 2D Physics inGodot 🚀 • Adds realism to games. • Handles forces and movement. • Controls collisions. • Essential for gameplay.
- 17. Physics Nodes • RigidBody2D= physics driven. • StaticBody2D = static object. • Area2D = detect overlaps. • Each node has unique use.
- 18. Collision Shapes • CollisionShape2Dis basic. • CollisionPolygon2D is custom. • Defines interaction area. • Shapes must fit objects.
- 19. Physics Materials • Adjustfriction property. • Adjust bounce property. • Material affects movement. • Improves game realism.
- 20. Gravity & Forces •Bodies respond to gravity. • Apply forces in code. • Use impulses for actions. • Mimics real physics.
- 21. Physics Process • Use_physics_process(delta). • Runs at fixed intervals. • Keeps physics consistent. • Better for movement.
- 22. Joints & Constraints •PinJoint2D connects bodies. • Keeps them linked. • Useful for mechanics. • Prevents drift.
- 23. Area2D Triggers • Detectsbody entered signal. • Detects body exited signal. • Triggers events in area. • Great for sensors.
- 24. Movement & Collisions •KinematicBody2D uses move_and_slide. • Handles smooth movement. • Detects collisions. • Prevents overlap.
- 25. Layers & Masks •Control collision layers. • Organize interactions. • Filter collisions easily. • Helps performance.
- 26. Performance • Simplify collisionshapes. • Avoid too many nodes. • Keep physics efficient. • Improves game speed.
- 27. Debugging • Enable visiblecollision shapes. • Print debug info. • Use debugger tools. • Fix overlaps.
- 28. Tips ⚠️ • Avoidoverlap bugs. • Use correct body type. • Test frequently. • Keep nodes simple.
- 29. Video Example • WatchGodot Physics tutorial. • Covers collisions and forces. • Demonstrates physics nodes. • Shows Area2D in action.
- 30. Summary 🌟 • Physicsadds realism. • Events connect gameplay. • Both are core to Godot. • Essential for fun games.
