compare types

This doesn't seem to be working. So how do I check if test1 and test2 are the same or not the same without throwing in some "Field ID" in the definition of Type Test. I though this would work but it doesn't work in code I'm working on.

for this1.Test Each Test

   for this2.Test = Each Test

      if (this1 = this2) then 
         ; do something
      end if

   next

next 

AFAIK, you can't nest type loops.

And what would happen if you did? As far as I know you can nest them since I have done that before and it worked. But how do you compare them? Anyone knows`?

In that code you're just comparing the type handles. To actually compare the contents (fields) of types, you have to do it manually i.e. compare each field.

[edit] Also, using a nested loop like that will mean you will be comparing a type instance with itself at times, which will always match. :)

Just an example of how I do it. This way cuts the comparisons down a fair bit.

For b1.body = Each body
		b2.body = b1
		While b2 <> Last body
			b2 = After b2
			distance# = EntityDistance( b1\entity , b2\entity )
			If Distance < ( b1\BT\Radius + b2\BT\Radius ) And ( b1\Collider And b2\Collider )
				COLLISIONcheck( b1 , b2 )
				COLLISIONcheck( b2 , b1 )
			EndIf
		Wend
	Next

nice, just what I looked for :) thanks for the example.

>you have to do it manually i.e. compare each field.

I did that and for some reason it didn't work, it match true even it if was not the case.

You can nest type loops. Your code at the top of the page has a bug in the first line: missing "=" sign.

I really don't know why people reply with wrong information when they obviously don't know the answer.

Type myType
	Field name$
End Type


a.myType = New myType
a\name = "a"

b.myType = New myType
b\name = "b"


For c.myType = Each myType
	For d.myType = Each myType
		If c = d
			Print "found type objects "+c\name+" and "+d\name
		EndIf
	Next
Next
WaitKey
End

Uh? Maximo did say "nice, just what I looked for". I know his first post looks like he wants to compare type handles but I deduced that's not what he wanted as it - and your example - are pointless because one type's handle will never match another type's. :)

I didn't mean you. :) I actually only meant BlackD. Sorry if I offended anyone else.

But it is still true that his code would not have worked either way cos of the missing =.

Not offended, just a bit confused. :P

I can't argue with that. :)
