function for type collide...

Ok heres the thing... i just begining a project game that is basicly you running around a world being able to shoot things with various weapons, pick up items, blah blah..
i wanted to make a function called "Is_Hit()" that would go something like:

Function Is_Hit(entity)
	If EntityDistance (player1,entity) <= 1 Then
		Return True
		Else
		Return False
	EndIf
End Function  

Now I want to use it in a function like:

Function UpdateItems()
	For item.Items = Each Items
		If Is_Hit(????) Then
		ityp=item\typ
			Select ityp
				Case 0
				;do stuff if its a collectable for points
				Case 1
				;do stuff if its a powerup
				Case 2
				;do stuff if its a weapon
				Case ;3,4,5...blah
			End Select
		EndIf

		;do other stuff like rotating objects and distance fading

	Next
End Function 

Now what do i put in the ???? area above to pass the courent type to the function? Also it this a good start to A pickups function?

Thanks all.

It depends what fields you have in your TYPE definition? But you need to pass the entity or mesh, so something like 'Item\Mesh' I guess.

Btw, have you considered using 'Collisions' to detect this instead?

Yah this part of my code is realy just psudo-code and im jeting some rules set down so i can design parts around them. the types just for this example asume anything you want. And as for the collisions, sure i could do that, i figured on this distance one so it would effectively create a "bubble" around a player so you wouldnt need to totaly match the items x,y,z to have an effect. Also i thought it would sorta "jump start" the pickup prossess if i have an animation for it. Its all in exparamentation night now.
(+i need to work on my Collisions :P )


But lets see.. for the ??? i would need to put "item" maby? because the courently selected item could be refrenced by that word? or should i use "this"?
(was looking as some code and saw some use of this in a select/case situation)

Ok, here is an example TYPE definition

TYPE Item
Field Mesh%
Field Typ%
END TYPE

Some constants to make code clearer

Const HealthPack% = 1
Const Ammo% = 2
etc

Then to create a new instance of that type

Local Thing.Item = New Item
Thing\Mesh = LoadMesh("HealthPack.b3d")
Thing\Typ = HealthPack

Then to check for collision

If IsHit(Thing\Mesh) Then

Select Thing\Typ
Case HealthPack
;do stuff for health pack pickup

etc

Hope that helps,
