An image is a box with a texture.

Example code

	src: "logo.png";
	x: 20;
	y: 10;
}

Virtual variables

  • componentId

    Type: vvar.i64

    The identifier of the data for this image.

    app.imgs[@self.componentId].width: value;

  • width

    Type: vvar.f32

    How wide the image is.

    theImage.width: 100;

  • height

    Type: vvar.f32

    How tall the image is.

    var height: theImage.height;

  • x

    Type: vvar.f32

    The position along the horizontal axis.

    theImage.x +: 100;

  • y

    Type: vvar.f32

    The position along the vertical axis.

    theImage.y -: 20;

  • z

    Type: vvar.f32

    The position along the direction of the depth.

    theImage.z: 0;

  • velocity

    Type: vvar.@vel

    The speed at which this image should move, in pixels per 60th of a second.

    theImage.velocity: @vel { x: 3; y: 5 };

  • src

    Type: vvar.ptr(@string)

    A string containing the file path for the resource. Returns the string as a cstr.

    theImage.src: "sprite.png";

Member variables

  • super

    Type: var.@element
