/*:
 * @plugindesc Allows animating pictures
 * @author Astfgl
 * @help
 * ===================================================================
 * Animation setup:
 * ===================================================================
 * First, setup the pictures using the event commands.
 * Then use the following script call:
 * $gameScreen.picture(pictureId).setAnim([array],interval);
 * Replace array by the file names without the extension, surrounded by "" and
 * separated by ",".
 * Ex: ["mouth_closed","mouth_1","mouth_2","mouth_3"]
 * These will be, in order the pictures displayed for the animations.
 * The first picture will be used when the animation is paused.
 *
 * Then replace interval by a number, this will be the number of frames
 * between image changes.
 * Ex: 5
 *
 * Ex: $gameScreen.picture(2).setAnim(["mouth_closed","mouth_1","mouth_2","mouth_3"],5)
 * This will cause the picture to loop between the frames you set in the array
 * until told to stop.
 *
 * ===================================================================
 * Freezing an animation
 * ===================================================================
 * You can tell a picture to stop looping by using:
 * $gameScreen.picture(pictureId).freeze();
 * It will set the picture to the first image in the list and stop it from looping.
 * Notice: when synching the animation to a message, it will freeze and unfreeze the
 * animation automatically when the message pauses. So you have to remove the animation
 * if you don't want it synching with a message, not freeze it.
 * This command is for out of message use.
 *
 * You can tell a picture to begin looping again by using:
 * $gameScreen.picture(pictureId).unfreeze();
 * This will make the picture start looping again, starting at the first frame.
 * Again, same disclaimer as for the freeze command: intended for out of message use.
 *
 * ===================================================================
 * Synchronizing an animation with a message box
 * ===================================================================
 * In order to synch up a picture looping animation to a message window use:
 * $gameMessage.setAnim(pictureId)
 *
 * Ex: $gameMessage.setAnim(2)
 * This will cause the picture to synch up its looping animation with the message
 * window: it will loop while text is writing, stop for pauses and between windows.
 * Using fast forward will make it skip the animation altogether.
 *
 * If you want a picture to no longer synch up with the message window, use:
 * $gameMessage.removeAnim(pictureId)
 *
 * Ex: $gameMessage.removeAnim(2)
 *
 * ===================================================================
 * Frozen or message end picture outside of animation loop
 * ===================================================================
 * By default the plugin will use the first image in the array as the frozen or
 * message end picture. If you would like to define a frozen picture outside of
 * the loop you can use the following command:
 * $gameScreen.picture(pictureId).setFrozenBmp(filename);
 *
 * Ex: $gameScreen.picture(2).setFrozenBmp("mouth_closed")
 *
 * If you would like to remove a frozen picture and start using the first picture
 * of the loop again, use the following command:
 *
 * $gameScreen.picture(pictureId).removeFrozenBmp()
 *
 * Ex: $gameScreen.picture(2).removeFrozenBmp()
 * ===================================================================
 * Wait time in between animation loops:
 * ===================================================================
 * If you want to pause the picture in between loops, use the following:
 * $gameScreen.picture(pictureId).setLoopInterval(number)
 *
 * Ex: $gameScreen.picture(2).setLoopInterval(60)
 * This will make the picture wait 60 frames before each animation loop.
 *
 * If you want to remove the wait between loops, use:
 * $gameScreen.picture(pictureId).removeLoopInterval();
 *
 * Ex: $gameScreen.picture(2).removeLoopInterval();
 *
 * Both of these commands are intended for out of message use.
 *
 * ===================================================================
 * Run animation loop only X times:
 * ===================================================================
 * If you'd like the animation loop to only run on certain amount of
 * times, use:
 * $gameScreen.picture(pictureId).setLoopTimes(number)
 *
 * Ex: $gameScreen.picture(2).setLoopTimes(5)
 * This will cause the picture to loop 5 times and them freeze itself,
 * until the loop times are removed or set again.
 *
 * If you want to remove the limitation, use:
 * $gameScreen.picture(pictureId).removeLoopTimes();
 *
 * Ex: $gameScreen.picture(2).removeLoopTimes();
 *
 * Both of these commands are intended for out of message use.
 *
 *
 * ===================================================================
 * Changing the frame Rate
 * ===================================================================
 * If you'd like to change the frame rate of the picture you can use the
 * following command:
 *
 * $gameScreen.picture(pictureId).setFrameRate(number)
 *
 * Ex: $gameScreen.picture(2).setFrameRate(10)
 * This will set picture 2 framerate to 10.
 *
 * ===================================================================
 * Text codes:
 * ===================================================================
 * This will also add several escape codes to use with message boxes:
 * \fa[pictureId] this will freeze the target picture animation. Again, if the animation
 * is synched it won't have any effect.
 *
 * \ufa[pictureId] this will unfreeze the target picture animation. Just as above,
 * if the animation is synched it won't have any effect.
 *
 * \da[pictureId] this will desynchronise the target picture animation with the
 * message window and automatically freeze it. Unfreeze it after if you'd rather
 * it kept running.
 *
 * \sa[pictureId] this will synchronize the target picture animation with the
 * message window.
 *
 * \ca[variableId] this will create an animation, you must have a picture already shown.
 * First you must setup a variable using the control variable: script command
 * the following way:
 * Control variables: script: [id,[spriteArray],interval,frozenBmp*,loopInterval*,loopTimes*].
 * Replace id by the picture id you want to animate.
 * Replace sprite array by the array of sprite names.
 * Replace interval by a number.
 * frozenBmp can be omitted, if it is present it will set the new animation to use
 * the file name you replace frozenBmp by as its frozen frame.
 * loopInterval can be omitted but you must provide a frozenBmp to be able to use it
 * it will set a wait time between loops, replace it with a number.
 * loopTimes can be omitted but you must provide a  frozenBmp and a loopInterval to
 * be able to use it. Replace it with a number, this will be the number of times the
 * animation will repeat.
 *
 * Ex: Control variables: script:[1,["mouth_closed","mouth_1","mouth_2","mouth_3"],5,"mouth_frozen"];
 * Then in the message use \ca[variableId], replacing variableId by the id of the
 * variable you just used.
 * So if you used variable 1, use \ca[1].
 * This will start the animation on target picture (1 here) using the sprites in the array,
 * and the interval there too, when the message reaches that point.
 * It will also synchronize it automatically.
 *
 * ===================================================================
 * Saving and loading animated pictures
 * ===================================================================
 * As of v12, there should no longer be a bug when saving pictures.
 * This is thanks to user kako05 on rpgmakerweb.com forums who commissionned
 * me for a fix.
 * ===================================================================
 * VN Commands
 * ===================================================================
 * As of V13, several VN like commands have been added to facilitate your life.
 *
 * -------------------------------------------------------------------
 * Light picture:
 * This will set the picture tone to (0,0,0,0), basically fully bright, over
 * the course of 30frames, acting like if the bust was selected.
 *
 * Script call:
 * $gameScreen.picture(id).light(duration)
 * duration is optionnal, if unspecified, will do it over 30 frames.
 *
 * Text code:
 * \LP[pictureId]
 * You can't specifiy a duration if doing it via textcode.
 * -------------------------------------------------------------------
 * Dim picture:
 * This will set the picture tone to (0,0,0,255), basically fully grey, over
 * the course of 30frames, acting like if the bust was unselected.
 *
 * Script call:
 * $gameScreen.picture(id).dim(duration)
 * duration is optionnal, if unspecified, will do it over 30 frames.
 *
 * Text code:
 * \DP[pictureId]
 * You can't specifiy a duration if doing it via textcode.
 * -------------------------------------------------------------------
 * Move picture home:
 * This will set  move the picture to its original coordinates over the
 * course of 30 frames.
 *
 * Script call:
 * $gameScreen.picture(id).moveHome(duration)
 * duration is optionnal, if unspecified, will do it over 30 frames.
 *
 * Text code:
 * \MPH[pictureId]
 * You can't specifiy a duration if doing it via textcode.
 * -------------------------------------------------------------------
 * Fadeout picture:
 * This will move the picture back 20 pixels in either direction,
 * set its tone to grey, and change its opacity to 0 over the course of
 * 30 frames before deleting it, erasing the bust from the screen.
 *
 * Script call:
 * $gameScreen.picture(id).fadeout(duration,direction,distance)
 * duration is optionnal, if unspecified, will do it over 30 frames.
 * direction is optionnal as well, 1 will move the picture left, -1 right.
 * distance is optionnal and is to be given in pixels
 * If you want to specifiy a direction, you must specify a duration.
 * If you want to specify a distance you must specify both other parameters.
 * You can only specify a duration if you want to.
 *
 * Text code:
 * \CPR[pictureId] this will fadeout the picture to the right
 * \CPL[pictureId] this will fadeout the picture to the left
 * You can't specifiy a duration if doing it via textcode.
 * -------------------------------------------------------------------
 * Fadein picture:
 * This will move the picture forward 20 pixels in either direction,
 * set its tone to bright, and change its opacity to 255 over the course of
 * 30 frames, acting as if the picture appeared.
 *
 * Script call:
 * $gameScreen.picture(id).fadein(duration,direction,distance)
 * duration is optionnal, if unspecified, will do it over 30 frames.
 * direction is optionnal as well, 1 will move the picture left, -1 right.
 * distance is optionnal and is to be given in pixels
 * If you want to specify a distance you must specify both other parameters.
 * If you want to specifiy a direction, you must specify a duration.
 * You can only specify a duration if you want to.
 *
 * Text code:
 * \FPR[pictureId] this will fadeout the picture to the right
 * \FPL[pictureId] this will fadeout the picture to the left
 * You can't specifiy a duration if doing it via textcode.
 * -------------------------------------------------------------------
 * Move picture:
 * This will move the picture relatively to its current position.
 *
 * Script call:
 * $gameScreen.picture(id).movePictureRel(x,y,t)
 * x and y are the amount of pixels you want the picture to move
 * t is the duration in frames
 * y and t are optionnal, if omitted the picture won't move on the y
 * axis and the x movement will be done over 30 frames.
 *
 * Text code:
 * \MPR[pictureId,x,y,t]
