[Closed] question about array

Sep 01, 2010 11:05 pm

I’m trying to create a button that generates spheres… and these spheres are part of an array, a second button to delete all spheres at once.

this is code:


rollout TestArray "Test Array"
(
	local objArray
	button b01 "Create"
	button b02 "Delete"
	
	on b01 pressed do 
	(
		ObjArray = #()
		ObjTest = Sphere()
		append ObjArray ObjTest		
	)
	on b02 pressed do
	(
		delete ObjArray
	)
)
createDialog TestArray

Only deletes last sphere, why?

rollout TestArray "Test Array"
 (
 	[b]local objArray = #()[/b]
 	button b01 "Create"
 	button b02 "Delete"
 	
 	on b01 pressed do 
 	(
 		ObjTest = Sphere()
 		append ObjArray ObjTest		
 	)
 	on b02 pressed do
 	(
 		delete objArray
 		[b]objArray = #()[/b]
 	)
 )
 createDialog TestArray

On your old script, everytime you created a new sphere you called objArray = #() which resets the array. So the array would always have one item no matter how many spheres you were creating. So I just got rid of that line, and also added a line to reset the array after you deleted it (otherwise it crashes if you hit delete twice)
