Look through the tutorial above, And also do some forum searches, And you will find tons of info on types.
Here are some basics:
First, you need To set it up like this.
Type Bullet
Field X_position
Field Y_position
End Type
What I have done there is To create a type called "bullet" and within that type there are two variables. (X_position, Y_position)
Now when you are ready to create a type, you do this.
b.bullet = new bullet
This creates a new bullet type with the name "b". The actual name used is not that important as you will see in a little bit.
Now we need to assign values to the fields.
b\X_position = mouseX()
b\Y_position = mouseY()
What I have done there is assign the bullet position to the mouse coordinates on the screen.
to delete this type, you do this.
delete b
Here is a small example of how you can use these. This is in 2d to keep the code as small and simple as possible.
Graphics 640,480,0,2
SetBuffer BackBuffer()
Type Bullet
Field X_position
Field Y_position
End Type
While Not KeyHit(1) ; loop until esc key is hit
If MouseHit(1) ; if the mouse button 1 is clicked, create a bullet and place it at the mouse postion
b.bullet = New bullet
b\X_position = MouseX()
b\Y_position = MouseY()
EndIf
For b.bullet = Each bullet ;loop through all bullets
Plot b\X_position,b\Y_position ;draw a dot on the screen at the bullet position
b\Y_position = b\Y_position -5 ;move the dot up the screen 5 pixels
If b\Y_position < 50
Text b\x_position,b\y_position,"/*\" ,1
Delete b ;delete the bullet when it reaches 50 in the X
EndIf
Next
Flip
Cls
Wend ; end main loop
End ;end program
