Phaser 4 Cameras

// In a Scene's create() method:

// Access the default camera (created automatically)
const cam = this.cameras.main;

// Scroll the camera to look at a different part of the world
cam.setScroll(200, 100);

// Center camera on a world coordinate
cam.centerOn(400, 300);

// Zoom in (2x) -- values < 1 zoom out, > 1 zoom in
cam.setZoom(2);

// Follow a sprite with smooth lerp
cam.startFollow(player, false, 0.1, 0.1);

// Constrain the camera to the world bounds
cam.setBounds(0, 0, 2048, 2048);

// Fade in from black over 1 second
cam.fadeIn(1000);

// Add a filter to the camera (v4 feature)
cam.filters.external.addBlur(1, 2);

// The manager is at this.cameras (not this.camera)
this.cameras              // CameraManager instance
this.cameras.cameras      // Array of Camera objects (render order)
this.cameras.main         // Reference to the "main" camera (first one by default)
this.cameras.default      // Un-transformed utility camera (not in the cameras array)

// Viewport: a 320x200 mini-map in the top-right corner
const miniCam = this.cameras.add(480, 0, 320, 200);

// Scroll: make the mini-map look at a different world area
miniCam.setScroll(1000, 500);

// Zoom: the mini-cam shows more of the world
miniCam.setZoom(0.25);

const view = cam.worldView; // { x, y, width, height }

// Direct property access
cam.scrollX = 100;
cam.scrollY = 200;

// Chainable setter
cam.setScroll(100, 200);

// Center the camera on a world coordinate
cam.centerOn(500, 400);

// Get the scroll values needed to center on a point (without moving)
const point = cam.getScroll(500, 400); // returns Vector2

// Instant follow (lerp = 1, the default)
cam.startFollow(player);

// Smooth follow with lerp (0..1, lower = smoother)
cam.startFollow(player, false, 0.1, 0.1);

// Full signature:
// startFollow(target, roundPixels?, lerpX?, lerpY?, offsetX?, offsetY?)
cam.startFollow(player, true, 0.05, 0.05, 0, -50);

// Change lerp or offset after starting follow
cam.setLerp(0.08, 0.08);
cam.setFollowOffset(0, -50);

// Dead zone: camera only scrolls when target leaves this rectangle
cam.setDeadzone(200, 150);

// Stop following
cam.stopFollow();

// Uniform zoom
cam.setZoom(2);       // 2x zoom in
cam.setZoom(0.5);     // zoom out (see twice as much)

// Independent horizontal/vertical zoom
cam.setZoom(2, 1);    // stretch horizontally

// Read current zoom
cam.zoom;    // shortcut -- reads zoomX (assumes uniform)
cam.zoomX;
cam.zoomY;

// Constrain scrolling to a world area
cam.setBounds(0, 0, worldWidth, worldHeight);

// Center on the new bounds immediately
cam.setBounds(0, 0, 2048, 2048, true);

// Temporarily disable bounds without removing them
cam.useBounds = false;

// Remove bounds entirely
cam.removeBounds();

// Read the current bounds
const rect = cam.getBounds(); // returns a new Rectangle copy

// Full-screen main camera
const main = this.cameras.main;

// Mini-map in top-right corner
const minimap = this.cameras.add(600, 0, 200, 150).setZoom(0.2).setName('minimap');
minimap.setScroll(0, 0);
minimap.setBackgroundColor('rgba(0,0,0,0.5)');

// HUD camera that doesn't scroll (ignores world objects, shows HUD layer only)
const hudCam = this.cameras.add(0, 0, 800, 600).setName('hud');
hudCam.setScroll(0, 0);

// Make the main camera ignore HUD objects
main.ignore(hudGroup);
// Make the HUD camera ignore world objects
hudCam.ignore(worldGroup);

// Find a camera by name
const found = this.cameras.getCamera('minimap');

// Remove a camera
this.cameras.remove(minimap);

// Fade out to black over 1 second
cam.fadeOut(1000);

// Fade out to red
cam.fadeOut(1000, 255, 0, 0);

// Fade in from black over 500ms
cam.fadeIn(500);

// Lower-level: fade (out direction) and fadeFrom (in direction)
// with a force parameter
cam.fade(1000, 0, 0, 0, true);       // force start even if running
cam.fadeFrom(1000, 0, 0, 0, true);

// With per-frame callback
cam.fadeOut(1000, 0, 0, 0, (cam, progress) => {
    // progress goes from 0 to 1
});

// White flash over 250ms (default)
cam.flash(250);

// Red flash over 500ms
cam.flash(500, 255, 0, 0);

// Full signature: flash(duration?, r?, g?, b?, force?, callback?, context?)
cam.flash(300, 255, 255, 255, true, (cam, progress) => {});

// Default shake: 100ms at intensity 0.05
cam.shake(100);

// Stronger shake for 500ms
cam.shake(500, 0.02);

// Independent x/y intensity using a Vector2
cam.shake(300, new Phaser.Math.Vector2(0.1, 0.02));

// Full signature: shake(duration?, intensity?, force?, callback?, context?)

// Pan camera center to world coordinate (400, 300) over 2 seconds
cam.pan(400, 300, 2000);

// With easing
cam.pan(400, 300, 2000, 'Power2');

// Full signature: pan(x, y, duration?, ease?, force?, callback?, context?)
cam.pan(800, 600, 1500, 'Sine.easeInOut', false, (cam, progress, x, y) => {});

// Animate zoom to 2x over 1 second
cam.zoomTo(2, 1000);

// With easing
cam.zoomTo(0.5, 2000, 'Cubic.easeOut');

// Full signature: zoomTo(zoom, duration?, ease?, force?, callback?, context?)
