+Pong isn't much without a ball. Let's get started on that.
+
+Fortunately there is a lot of stuff we can re-use already. That's the power of Encompass!

+
+const ball_position_component = ball_entity.add_component(PositionComponent);

+
+OK. We're both thinking it. Why is all this crap going straight in **game.ts**? And there's magic values everywhere! You are absolutely right. Encompass actually has a built-in abstraction Engine for creating new Entities called a Spawner. Let's use one.
+
+Let's create a new folder: **game/engines/spawners**
+
+And a new file: **game/engines/spawners/ball.ts**
+
+```ts
+import { Reads, Spawner } from "encompass-ecs";
+import { CanvasComponent } from "game/components/canvas";
+import { PositionComponent } from "game/components/position";
+import { BallSpawnMessage } from "game/messages/ball_spawn";
+
+@Reads(BallSpawnMessage)
+export class BallSpawner extends Spawner {
+    public spawn_message_type = BallSpawnMessage;
+
+    public spawn(message: BallSpawnMessage) {
+        const ball_entity = this.create_entity();
+
+        const ball_position_component = ball_entity.add_component(PositionComponent);
+        ball_position_component.x = message.x;
+        ball_position_component.y = message.y;
+
+        const ball_canvas = love.graphics.newCanvas(message.size, message.size);
+        love.graphics.setCanvas(ball_canvas);
+        love.graphics.setBlendMode("alpha");
+        love.graphics.setColor(1, 1, 1, 1);
+        love.graphics.rectangle("fill", 0, 0, message.size, message.size);
+        love.graphics.setCanvas();
+
+        const ball_canvas_component = ball_entity.add_component(CanvasComponent);
+        ball_canvas_component.canvas = ball_canvas;
+        ball_canvas_component.x_scale = 1;
+        ball_canvas_component.y_scale = 1;
+    }
+}
+```
+
+Spawners aren't very complicated. They have one required property and method: *spawn_message_type* and *spawn*.
+
+When the Spawner reads a message of *spawn_message_type*, it runs its spawn method once. Simple as that.
+
+Now let's actually send out the BallSpawnMessage.
+
+In **game/game.ts**...
+
+```ts
+...
+
+    world_builder.add_engine(BallSpawner);
+
+...
+
+    const ball_spawn_message = world_builder.emit_message(BallSpawnMessage);
+    ball_spawn_message.x = 640;
+    ball_spawn_message.y = 360;
+    ball_spawn_message.size = 16;
+
+...
+```

+
+Well, it draws, but it's a bit boring without any movement. Let's make it move around.
