Triangle

Introduction¶

Triangle shape, built-in game object of phaser.

Author: Richard Davey

Usage¶

Create shape object¶

var triangle = scene.add.triangle(x, y, x1, y1, x2, y2, x3, y3, fillColor);
// var triangle = scene.add.triangle(x, y, x1, y1, x2, y2, x3, y3, fillColor, fillAlpha);

Custom class¶

Define class

class MyTriangle extends Phaser.GameObjects.Triangle {
    constructor(scene, x, y, x1, y1, x2, y2, x3, y3, fillColor) {
        super(scene, x, y, x1, y1, x2, y2, x3, y3, fillColor);
        // ...
        scene.add.existing(this);
    }
    // ...

    // preUpdate(time, delta) {}
}

scene.add.existing(gameObject) : Adds an existing Game Object to this Scene.
- If the Game Object renders, it will be added to the Display List.
- If it has a preUpdate method, it will be added to the Update List.

Create instance

var triangle = new MyTriangle(scene, x, y, x1, y1, x2, y2, x3, y3, fillColor);

Color¶

Fill color

Get

var color = triangle.fillColor;
var alpha = triangle.fillAlpha;

Set
```
triangle.setFillStyle(color, alpha);
```
Clear
```
triangle.setFillStyle();
```

Stroke color

Get
```
var color = triangle.strokeColor;
```

Set

triangle.setStrokeStyle(lineWidth, color, alpha);

Clear
```
triangle.setStrokeStyle();
```

No tint methods

Uses triangle.setFillStyle(color, alpha) to change color.

Alpha¶

Get
```
var alpha = triangle.alpha;
```

Set

triangle.setAlpha(alpha);
// triangle.alpha = alpha;

Set vertices¶

triangle.setTo(x1, y1, x2, y2, x3, y3);

Triangle width¶

triangle.setLineWidth(startWidth, endWidth);

endWidth : The end width of the triangle. Only used in WebGL.

Display size¶

Get

var width = triangle.displayWidth;
var height = triangle.displayHeight;

Set

triangle.setDisplaySize(width, height);

or

triangle.displayWidth = width;
triangle.displayHeight = height;

Other properties¶

Create mask¶

var mask = triangle.createGeometryMask();
