Ingame Commands

Allow the user to interact with the RAM from the listening session by inputting /[command] during listening.

See vignette("rrio") to see these in action.

Usage

inputs.command(RAM, command)

Arguments

RAM

RAM object.

command

Command to use; parsed from inputs.csv.

Details

These commands are generally useful to debugging or testing parts of a game that are difficult to test at full speed. Alternatively, greater control can be achieved by using the display session and manually interacting with the game with:

RAM = ram.input(RAM, [input])
RAM = ram.tick(RAM)
render.ram(RAM)

Which also allows the user to copy and restore RAMs as savestates, etc.

Commands

/pause		Pauses the RAM without stopping the gameloop.
/resume		Resumes the game if paused.
/tick		Iterates the RAM one tick, as if ram.tick() had been called in the display session.
/rollback		Forces a rollback, and draws if the game is paused.

If the game is paused and an input is entered, it will be processed next /tick or when the game resumes. This allows the player to play a game frame-by-frame.

Examples

if (FALSE) { # \dontrun{
quickload(Snake)
#in a separate R session:
inputs.listen()
#now input these lines:
#/pause
#  (one space)
#/tick
#/tick
#/tick
#/resume
} # }
