Explanation of screen

PC and Tablet (landscape) version

Figure  shows a screenshot when the application is accessed using a PC browser.

The screen consists of three parts. The upper left is the “pictogram display area” for displaying pictograms, the upper right is the “program code input area” for describing programs, and the lower is the “program code input assist button” for supporting program input.

The pose of the human shaped pictogram can be changed or moved by entering a program in the program code description area. You can also add the statement to the “Program code input area” by pressing the “Program code input assist button”. Code can be written in three languages: English, Japanese (Kanji), and Japanese (Hiragana). By selecting from the “Language selection” pull-down, the language displayed on the “Program code input assisrt button” has changed.

Options according to the purpose of use

You can turn on and off four functions according to the purpose of use.

Icon(Name) Explanation
(Show coordinate system) When the check box displayed on the right of the image is turned on, the coordinate system is displayed. The coordinates are in the XY coordinate system (the X and Y values are combined to represent the position). The horizontal direction is the X coordinate from the left end -320 to the right end 320, and the vertical direction is the Y coordinate from the upper end -320 to the lower end 320. That is, the center is (0,0), the upper left is (-320, -320), the upper right is (320, -320), the upper left is (-320, -320), the upper right is (320, -320).
(Hide program code input area) When the check box displayed on the right of the image is turned on, the “Program code input area” is hidden. Use this when you want to create a pictogram just by dragging the mouse, such as when designing classes or when young children use it.
(No mouse dragging)*default ON When the check box displayed to the right of the image is turned off, the human shaped pictogram can be operated by dragging the body part of the pictogram directly on the “Pictogram display area”. You can also draw a line segment by dragging the start point to a point other than the body part of the human shaped pictogram.
(No play by return key)*default ON When the check box displayed on the right of the image is turned on, the program will be executed only when “Play” button was pressed. On the other hand, the program will be executed when a line feed code is entered (pressing the Enter key) in the “Program code input area” if the check box is turned off.

 

Control buttons

Playback, stop and so on are controlled from the control buttons.

Icon(Name) Explanation
(Play) Play the animation from the beginning.
(Fast forwarding) Fast forward playback from the beginning. Useful for getting an overview when the overall execution time is long.
(Stop) Stop the animation.
(Replay) Play the animation from stopped state.
(Clear all) Clear the program written in the “program code input area”. A confirmation dialog box appears before erasing.

How to download contents

The application provides how to download contents in three ways.

[1. Download program code]

(1)  Input the title in “Title input” field.

(2) Press “Download button”,  and the code would be downloaded with a name of “title”.txt (here “title” is a name you inputted in “Title input” field.

[2. Download shot image]

(1) Press “Image download button”,  and the shot image would be downloaded with a name of “title”.png (here “title” is a name you inputted in “Title input” field.

[3. Download animation]

(1) Turn on the check button to the right of the video download button.

(2) Execute once from the beginning to the end. Although it runs slowly, animated image are generated dynamically.

(3) Press “Movie download button”,  and the animation file would be downloaded with a name of “title”.gif (here “title” is a name you inputted in “Title input” field.

 

 

Program Example

Operations on the human pictogram are input and defined in the program code description area (upper right of the figure ). The input string to change states (positions) follows a format that separates opcode and arguments with blanks, as follows.

opcode arg1 arg2 …

Figure on the right shows a sample code. Line 1 changes the scale of the human pictogram. Lines 2 to 8 are in accordance with the LOGO programmer; this draws a rectangle that represents the victor’s platform. The “M(ove)” command shown in line 10 means move 50 px in the positive x-axis direction and 200 px in the negative y-axis to get up on the box. The “R(otate)W(ait)” command means rotate a part of the body over some seconds and the next command is not executed until the movement is complete. For example, “RW LUA -120 1” shown in line 12 means “rotate the Left Upper Arm (LUA) 120° clockwise for 1 s.” Lines 13 to 19 represent waving the left hand three times at a probability of 50%

 

 

 

 

 

 

 

Command List

List of Pictogram Animation commands

Command Format

Process

R arg1 arg2 arg3 arg4

After arg4 seconds, rotate arg1, a part of the body, arg2 degrees counterclockwise over arg3 seconds. If arg4 is omitted, then arg4 is treated as 0. If arg3 and arg4 are omitted, the arg3 and arg4 are both treated as 0.

RW arg1 arg2 arg3

Rotate arg1, a part of the body, arg2 degrees counterclockwise over arg3  seconds.The next command is not executed until the movement is complete. If arg3 is omitted, then arg3 is treated as 0.

M arg1 arg2 arg3 arg4

After arg4 seconds, move arg1 pixels in an X-axis positive direction and arg2 pixels in a Y-axis positive direction with linear uniform motion over arg3 seconds. If arg4 is omitted, then arg4 is treated as 0. If arg3 and arg4 are omitted, then arg3 and arg4 are both treated as 0.

MW arg1 arg2 arg3

Move arg1 pixels in an X-axis positive direction and arg2 pixels in a Y-axis positive direction with linear uniform motion over arg3 seconds. The next command is not executed until the movement is complete. If arg3 is omitted, then arg3 is treated as 0.

FR

Switch the human pictogram to the front direction. (Initial state)

SD

Switch the human pictogram to the side direction.

C

Switch the human pictogram to the initial posture.

SC arg1

Change scale to arg1 time(s) from current size.

SP arg1

Human pictogram speaks a sentence arg1.

SAY arg1 arg2 arg3

After arg3 seconds, say arg1with balloon over arg2 seconds. If arg3 is omitted, then arg3 is treated as 0. If arg2 and arg3 are omitted, the arg2 and arg3 are both treated as 0.

SAYW arg1 arg2

Say arg1 with balloon over arg2 seconds.The next command is not executed until the saying is complete.

Command Format Process
PEN arg1 [arg2]

Release Pen  if arg1 is “RELEASE” or “UP”, hold pen if arg1 is “HOLD” or “DOWN.”

A part of body can be set as arg2 to set the location of releasing or holding the pen only if arg1 is “RELEASE”, “UP”, “HOLD” or “DOWN.”  IF arg2 is omitted, it is considered to set “BODY”.  Initial state of pen is released for all parts of body.

The shape of line’s both edges set square if arg1 is “SQUARE”, set round if arg1 is “ROUND”.

No shape is attached at both edges if arg1 is “BUTT”. As for kinds of pen, draw solid line if arg1 is “NORMAL”, erase line if arg 1 is “ERASE”, and erase the part already drawn and draws a part not so if arg1 is “XOR”.

Initial shape of line’s edge is square.
