First choose which type of detection you want: specific (text from one user only), local (text from current player only), shared (text from any player).
Then edit in.txt with the desired text in the following format depending on the type:

Specific:
username: text

Local:
 text

Shared:
text

The special character is there for a reason, copy and paste if you need to.

Run TextConv.exe once, no window should stay open. Copy the contents of out.txt and replace the first four lines of TextTrig.protrg with it. In the fifth line of TextTrig.protrg, edit the variable 'type' depending on which type you chose. Compile it with ProTRG.

Remember when in-game you have to append three spaces after the actual text for it to work. However, in.txt does not need the three appended spaces.
