The Sprite struct

The sprite struct is a basic structure that can be used in Xentu to draw all or part of a texture onto the screen. All you need to get started is a loaded texture, and an idea of where you want to draw it.

Sprite(texture, x, y, width, height)

The main constructor is used to create a sprite instance. For example:

ball_texture = assets.load_texture('ball.png', TX_RGBA, TX_REPEAT)
ball_sprite = Sprite(ball_texture, 0, 0, 100, 100)

Then in your render event you could draw it like this:

-- the drawing event.
game.on("draw", function()
        renderer.clear()
    renderer.begin()
    renderer.draw_sprite(ball_sprite)
    renderer.present()
end)

[instance].spritemap

If you wish to render only a region of the texture you’ve picked. You can use a loaded spritemap:

ball_sprite.spritemap = assets.load_spritemap('ball_sprites.json')

For more information, see The SpriteMap class.

[instance].region

Along with the spritemap property, you can also choose which region on the spritemap to use by providing a region name. By default this is set to ‘full’, which is a reserved region name which means the whole texture is used. However you can change it like so:

ball_sprite.region = "walk1"

This can be really useful for providing some basic animation for your game sprites. For more information, see The SpriteMap class.

[instance].x

The x property can be modified to move the sprite on the x-axis like so:

ball_sprite.x = ball_sprite.x + 10

[instance].y

The y property can be modified to move the sprite on the y-axis like so:

ball_sprite.y = ball_sprite.y + 10

[instance].width

The width property can be modified to change the width of the drawn sprite:

ball_sprite.width = 200

[instance].height

The height property can be modified to change the height of the drawn sprite:

ball_sprite.height = 200
