Hey, i've been reading about scripting, but i'm finding it difficult to understand how to get started.
Could someone provide a step by step guide?
Pick a project, make it as simple and easy as you can – really, really simple, even if it only changes "one thing", a single command such as inverting an image or running a filter.
Then read documentation and search the web (forums such as this, blogs etc) for real code samples to make a script to do that "one thing".
A script to do "one thing" may take a single line of code, or perhaps many!
Good luck, the forum is here to help.
You also need a text editor or IDE for your chosen scripting language.
Although a simple plain text editor is all you need for JS, a "coding" text editor with JS syntax highlighting is better. Better yet is something specific for Adobe script writing.
What OS and version do you use?
David's book is great. The scripting guides that Adobe provides are confusing and not always accurate.
