Types Question

I'm looking for the most efficient way of comparing all the instances of a type with each other without checking the same cobination twice.

This is how I'd do it with an array. Note that I don't want to have to make an array of types.

Blahs = 10
for b = 1 to Blahs-1
for c = b+1 to Blahs
compare ( b , c )
next
next

Cheers

There may be a more magical way around this...

What are you comparing them for?

It's a custom collision engine ...

Use an outer for each loop and an inner while loop to iterate types AFTER the current one while not null...

Type mytype
Field num
End Type

For i=1 To 7 
	m.mytype=New mytype
	m\num=i
Next


For b.mytype=Each mytype
	c.mytype=After b
	While c<>Null
		Print "Comparing "+b\num+","+c\num
		c=After c
	Wend
Next

WaitKey()

Got yee .. will give this a try .. should work.
