Here are detailed descriptions of some of the editing conveniences we provide.
Cut, copy, and paste
All of the regular cut, copy, and paste tools work inside Scripts. When you use them, they act on the selected Operator and all its arguments. Thus, you can move big chunks of script around with cut and past. Here's an example. Suppose that you realize that you need to reverse the order of subtraction in this Script:
so that the 0.5 is on top and the Blend is on the bottom. To do this, simply select the Blend Operator, cut, select the 0.5 Operator, and paste. Lastly, enter the 0.5 value in the upper slot.
Outsertion
If you select an Operator in a Script and hold down the Control key while choosing a new Operator from a Menu, that new Operator will be "outserted"—placed above the selected Operator. Here's an example.
Existing Script:
BSum of:
Fearful_Angry of:
Joe
0.5
Select Operator "BSum," then click on "BSum of:" and hold down the Control key while opening the Arithmetic menu. Select menu item "BInverse" and get this result:
BInverse of:
BSum of:
Fearful_Angry of:
Joe
0.5
You'll use outsertion quite often in your daily scripting work.
Replacement:
You can replace one Operator with another by holding down the Option key before opening a menu. Example:
Existing Script:
BSum of:
Fearful_Angry of:
Joe
0.50
Select the Operator BSum, then hold down Option and open Arithmetic menu, selecting "BDifference." Get new Script:
BDifference of:
Fearful_Angry of:
Joe
0.50
What's especially nice about this trick is that it preservers the arguments of the original Operator. If you used the direct route, you'd have to erase those internal arguments. This way, you don't erase them. There is a catch, however. You can't just replace any Operator with any other Operator. The only Operators that will be available for you to select are those whose argument types match the argument types of the original Operator.
This capability extends even to Operators with fewer or more than the number of arguments of the original Operator. For example, if you replace AND3 with AND4, the new AND4 will contain the previous three boolean arguments and add a fourth, undefined boolean Operator at the end. If you go in the other direction, replacing AND4 with AND3, then the last boolean argument will be deleted.
Collapsing a Script
Suppose you have this Script:
AND
AreSameActor of:
ThisSubject
ReactingActor
NOT
AreSameActor of:
ThisDirObject
CandidateActor
And you want to get rid of the first "AreSameActor" term. Just click on the NOT Operator, Copy, click on AND, and Paste. Now it reads:
NOT
AreSameActor of:
ThisDirObject
CandidateActor
Right-clicking
If you select an Operator and click on the right button on your mouse, then you'll see a long menu pop up next to the selected Operator, containing every single Operator that you could enter in its stead. Some of those Operators are placed inside submenus. (Mac users, you can reach the right-click/context-sensitive menu by holding down the Control key when clicking on the Operator. But the right-click is so heavily used by Swat that you really should buy a two-button mouse, such as the Apple Mighty Mouse.)
