Instead of Fast Loop

[ASD]

I joined another object to the object by using Fast Loop.

However, processing slows because the loop frequency increases, too, when the number of objects increases.

Is there a method of evading slowing of processing?

Use my Position Controller extension, it has features for object attachment.

I don't know usage of your extension.

Could you make example?

[Jaffob]

Yes, sure. Here is your example modified to compare fastloops (the 1st frame) to the Position Controller (2nd frame). You can set the global value "Number to make" through the application properties to the number of pairs of objects to make (it would be 230 in your original example).

Here is a list of framerates I got for different numbers to make:

Number to Make = 200:
Fastloop: 60 FPS
Pos. Controller: 60 FPS

Number to Make = 300:
Fastloop: 40 FPS
Pos. Controller: 60 FPS

Number to Make = 400:
Fastloop: 23 FPS
Pos. Controller: 60 FPS

Fast Loops and the MMF object selection scope tend to a time complexity of O(N^2) over N objects. The ForEach object, if you learn it, can operate in O(N) time, because it directly references the objects you want to use.

I'd strongly recommend trying to use the ForEach object for operating over a large set of objects

The Position Controller does the same thing, so for the sake of attachments it is better. But yes, for looping through objects in general the ForEach Object is a good way to go.

Thanks!
However, the application crashes when parent or child object is destroyed.

Moreover, can parent and child object tie?(example: when a parent object is clicked, the bullet is launched from the child object.)

You just found a bug. I'll have to fix that when I release a new version, but for now you can use either "Detach Single Object" or "Detach Children" on a child or parent before destroying them.

Moreover, can parent and child object tie?(example: when a parent object is clicked, the bullet is launched from the child object.)

Yes, you can. Try the following code:

-User clicks on "Parent"
-Fixed value of "Child" = AttGetChild( "Position Controller", Fixed("Parent"), 0):
    --Shoot Bullet from "Child"

Okay, I'm looking foward to update.

-Fixed value of "Child" = AttGetChild( "Position Controller", Fixed("Parent"), 0):

Very nice!

Can define the position of the child object related for the parent object? (Currently child object position is parent object hotspots)
