 So you want the particle sizes to get smaller towards the end of their life, not a problem. There is a module just for you that you can add right under the particle update called Scale Sprite Size. Set it to non-uniform curve and from here you will see a timeline. You can right click drag to pan the camera, scroll up and down to zoom in and out, right click anywhere on the timeline to add new points, and if you right click on a point you can change the type of curve shape or delete points whenever you want. You can also press space bar to activate your effect whenever you need to see it. And these little pins are used to hide the X and Y values so you can focus on one thing at a time. So let's hide the Y value for now so all we see is X. And what this line means is at zero seconds the value of X will be zero percent. But after one second the value of X will be a hundred percent. Now we don't really want our sparks squishing horizontally so we're just going to set everything to one. But what we do want is for them to shrink vertically as they die. So we're going to take a look at why the easiest way to do this would be to say at zero seconds Y should be one, but after one seconds we want Y to shrink down to zero. If you compile and save now you will see the length of your sparks get shorter after one second. All that helps as always so if you have a fantastic day and I'll see you around.
