The wait command updates the display for a specified number of wait-frames before allowing execution of the next command in a script. It can also be used to generate duplicate image frames in movies (like movie duplicate). See also: stop, making movies
Following certain multi-frame commands, wait without a number will automatically wait the needed number of frames for the command to finish (see the Chimera list of such commands; other commands require the number to be given explicitly). In the following example, wait prevents move from starting until roll has finished:
roll y 3 120
move x 0.2 75
It is also acceptable to give the frame argument where it could have been omitted (in the example, wait 120 instead of just wait).
Unlike Chimera, when executing a command file, ChimeraX does not add an implicit wait 1 at the end of each line that could change the display. Thus, after a series of commands is saved from the Command History or otherwise written to a text file to create a ChimeraX command script, it may be necessary to add wait or wait N commands between them (or appended to lines with a semicolon separator) to see the effects of individual commands as they are executed and/or enforce their ordered execution.
Stretches of duplicate image frames correspond to periods of time where objects remain static. If motion occurs in the last few frames of a movie, due to the encoding process it may appear to end on a blur. This effect can be avoided by including a few wait frames (wait 5 or similar) at the end of scripted movie content.
