Building a particle system
Before we start coding, it will be helpful to see exactly what it is we are trying to achieve. Take a look at the following screenshot:
This is a screenshot of the particle effect on a plain background. We will use the effect in our game.
The way we achieve the effect is as follows:
- Spawn 1,000 dots (particles), one on top of the other, at a chosen pixel position.
- In each frame of the game, move each of the 1,000 particles outward at a predetermined, but random, speed and angle.
- Repeat step two for two seconds and then make the particles disappear.
We will use a VertexArray to draw all the dots and the primitive type of
