`Particles tutorial

`After this tutorial, you'll have learned the basics of particles

sync on : sync rate 60 `set up our screen refresh rate

backdrop on `set up the 3D display

`The first number is the unique particle number that can only be set to one

`particle. The second number can be used for an image, yet we won't be needing one.

`The third part tells us how frequent we want the particles to occur. Finally,

`the radius tells the distance from the center of the particles they will fly out.

make particles 1,0,50,10

`For this tutorial we'll also include a second particle.

make particles 2,0,50,10

`Now lets color them to make things more interesting.

`As mentioned before, you can use and image instead of coloring them.

color particles 1,255,0,0

color particles 2,255,50,50

`Now we'll want to do something very simple. We'll rotate the particles

`This can be used to give an explosive effect when used correctly.

rotate particles 2,90,0,0

`We only need to rotate the second particle, sinc the other one is right side up already.

`We'll now set the particles life, for how long they'll live.

Set particle life 1,75

Set particle life 2,75

`We'll now set how fast the particles move

Set particle speed 1,0.004

Set particle speed 2,0.004

do `Initilize our loop

`Just a friendly reminder for when you're running the loop. :)

text 0,0,"Press spacebar to stop explosions"

`Now you can play around with the particles.

`If the spacekey is pressed it'll stop the particles,

`or ELSE, the particles will keep emitting. The emissions command

`can be a helpful way to create explosions in your games.

if spacekey()=1

set particle emissions 1,0

set particle emissions 2,0

else

set particle emissions 1,25

set particle emissions 2,25

endif

sync `Refresh the screen

loop `Loop the program

`Now you're free to play around with the particles as you like.

`I encourage you to tweak the values to your need, and take a look at

`the other help files for Particles and explore the new commands.

`Hope this helped
