/* NOTE: CommandExec and ProgramExec perform similar tasks on different data.
|
|
CommandExec executes commands found in location scripts, while ProgramExec
|
|
runs animation programs.
|
|
|
|
The main difference is how suspension is handled. CommandExec is coded with
|
|
the assumption that there may be at most one suspended list of commands at any
|
|
moment, and thus stores the suspended context itself. It also offers a
|
|
runSuspended() routine that resumes execution on request.
|
|
ProgramExec instead stores the suspension information in the programs themselves.
|
|
Programs are in fact meant to be run (almost) regularly on each frame .
