Last week I received the latest version of GameBuilder Studio beta version by signing up in their website http://gamebuilderstudio.com/. It is a very friendly and easy to use piece of software and when completed will be a must need flash game development editor. It uses all the concepts of push button saving a user all the coding and more time to the gaming. It incorporates are the essential PBE concepts levels, templates, pbe objects and when you export to Flash Builder it already generates a xml file for you, creating your game for you. By creating the templates and levels it saves vast amounts of coding for a developer. You can assign a background and foreground images by drop and drag from the assets which can be uploaded from your documents / pictures / images. It has quick objects you can pull to the screen as below I created this tree and 2 boxes from the quick objects at the side. There is a screen shot below.
The main developer is very cooperative and is willing to help you along the process to creating a project with his guidance if needed. Even in early beta version what I could do already would have saved me days of studying PBE but since it is only beta to make a game completely using it isn't possible yet the main reason as collision detection has not been addressed yet but from talking to Lavon it will be in future versions and has already done it just to release it. Also from talking to Lavon he revealed to me by the time the editor will be completed that you will be able to create the user interface also this will make creating a game a lot easier. All I can say as a negative towards GBS is that its not going to be completed in time to help my project which is a pity as it is the ideal software I was looking for since January.
