Build Helper Chat

Modified BuildHelper script to support chat commands to change the color and size of a prim. The built-in ChatCommands component model was used for this.

USAGE:
// 99 command command_parms

Processes the following commands.
- color aColor: Set the color of the prim to aColor.
- size x,y,z:      Set the size of the prim to the dimensions x, y & z.
- help:             Provide help on the commands supported.

Processing Chat Commands

A listen filter is set up to listen for chat in the pChatCommands state.

Then the listen event occurs as a result of someone chatting on the configured channel (default: 99), the chat text is parsed and split into a list containing the command and it's parameters.

Each command is then processed through the use of a Choice Point and it's outgoing transition, each of whose Guard Conditions detect a different command.
