Introduction

This script takes an isometric map(predetermined by the isometric view script) and renders you a png of it including heights. This makes it easier to develop isometric tilesets and overall isometric maps. Cause it does all the placement etc for you.

Features

• Renders Isomap to PNG file
  
• Replaceable default tiles (IsoNode.png in the Pictures folder)

Instructions

This script has a couple of requirements:

• SDK
  
• MACL
  
• Isometric View
  

It would be best to use the demo, but you would simply place this script in a project with the above required scripts (which are included in the demo) and transfer your player to a map including the name of ISO and it will be rendered for you to the Graphics\IsoMaps folder of your project.

FAQ
Its slow! while walking on the map!
None other than that. xD

Compatibility
This will not work in VX

Credits and Thanks
Makers of the SDK and MACL for giving me the ability to write to PNG file.
McCaladtogel for his original Isometric script, which I modified into Isometric Views (XP/VX)
Seigfried for his help in nailing down Isometric height movement.


Author's Notes
This script is only for RMXP and cannot be used inside of VX. However you can render your maps in XP, and import the made tilesets to VX.
I dont know of any compatiblity problems. However do keep in mind that this script displays 100's of sprites on screen at once. This causes major lag, but shouldnt really matter, because it is intended for game dev only. As in to render the maps for you, so that you can turn them into what you want.

Terms and Conditions
Intended for Development use only(cause its too slow otherwise). Please do not repost this script elsewhere without my permission.
