Rectangular flood fill: Create fill objects that cover the rectangular area of target objects

[tristanbob]

Describe the extension

Create fill objects that cover the rectangular area of target objects

How To Use:

• Place target objects in the scene in the places you want fill objects to be created
• This action only needs to be run once (at the beginning of the scene or using TriggerOnce)

Requirements:

• Extension "Create Multiple Copies of Object" must be installed

Object variables (Fill objects):

• "CreationID" (number)
• "RowID" (number)
• "ColumnID" (number)
• "BatchID" (text)

Tips:

• Use fill objects that are the same size as the scene editor grid. This will make sure the fill objects fit exactly inside the target objects.
• Hide target objects at the beginning of the scene if you don't want them to be visible.

Hi!

This extension requires another extension ("Create multiple copies of an object") in order to function correctly

So, why don't you add the that function to this extension and remove it when dependencies are automated? The create copies extension only has a single function so it should be relatively easy. I tested it and it works without a problem

• Adding a random fill might be useful. As it can be used to populate top down games with foliage, etc... it might be suited to make another extension. but, it is your choice

• One suggestion I would give is to change the icon, as the extension is a rectangular fill tool (and not a hexagonal fill), something like this would be more apt

:)

@Midhil457 thanks for your great insight. I have made the changes you recommended:

Version 1.1.0

• Changed icon to one of the grid icons
• Copy/Pasted the CreateMultipleCopiesOfObject Extension (and changed the reference to it)
• This means there is no longer an external dependency. Once dependencies are supported, we should change this extension to refer to other extension.

Hi again,

• You can make the MultipleCopies function private if you don't want the user to be able to use it or it to show up in the events selector

• One suggestion I forgot to add; The sentence in the events sheet could be

  Create PARAM2 that will cover PARAM1. Space between rows: PARAM3, columns: PARAM4 Layer: PARAM5 Z-order: PARAM6 BatchID: _PARAM7

  or

  Fill PARAM1 with PARAM2. Space between rows: PARAM3, columns: PARAM4 Layer: PARAM5 Z-order: PARAM6 BatchID: PARAM7

again it's your choice

:)

Very nice! (as usual :)) @tristanbob do you want to do these latest changes according to @Midhil457 feedback? Then we can go ahead and add this 👍👍

[tristanbob]

Yes, I do. I expect I will get this updated tonight!

[tristanbob]

Thank you @Midhil457 for helping polish this extension!

Version 1.1.1

• Changed "CreateMultipleCopies" function to private (so users don't get confused if they also have that extension installed)
• Cleaned up the event sentence a little by removing extra words: Create _PARAM2_ objects that will cover _PARAM1_ objects. Space between rows: _PARAM3_ Space between columns: _PARAM4_ Layer: _PARAM5_ Z-order: _PARAM6_ BatchID: _PARAM7_
