Just a few corrections to that Tricks.
SCAR is a program which can be told to click, type, search for a color, etc. (NORMALLY used to do repetitive tasks, but it can also be used, for example, to send a series of key strokes very quickly at the touch of a button, when you're pressed for time, such as if you're in a fight in some obscure game which requires you to type "V C A D" to eat something, it can type the keys almost instantaneously).
The name of the include is SRL, which stands for SRL Resource Library. Not the best name, but meh.
A few other things you may need are SMART (basically the rsclient with it's own mouse/keyboard), and reflection (let's you be almost 100% accurate 100% of the time), as you may be required by some scripts (for example, my Duel Arena Reflection version) to run.
SMART MUST be used when using Reflection, as SMART provides the information Reflection uses to move around, find objects, etc. Each time RS updates, Reflection must be updated, so if a script isn't working, either the script itself is outdated, or Reflection needs updating.
If you have any more questions, feel free to post, or pm someone here.
