Stops the currently running timer, if there is one.
This instruction has no parameters.
1: StopTimer;
If the currently running timer would’ve executed a frame at the end, it will not be executed if the timer is stopped with this instruction.
AACT’s text render abilities are very primitive at the moment. As such, there is currently no way to display a good looking timer text. A “DisplayTimer” instruction (which would display a text showing a countdown of the timer) will be added in a future version, after the text render abilities have been enhanced.
