This document describes the steps to create an animation of a moving smiley face and two moving balls using Raptor. It involves opening a graph window, setting coordinates for the objects, drawing the background and objects, and using loops to redraw and move the objects across the screen in each frame to create the animation effect. Key steps include initializing x and y coordinates, drawing the background and objects on each pass, changing the coordinates to move the objects, upgrading the graph window, and repeating in a loop until the animation is complete.

1. RAPTOR: ANIMATION
BY VITIAN ADARSH

2. DRAW SMILEY FACE
STEP 1:- START
STEP 2:- OPEN THE WINDOW
STEP 3:- DRAW THE BACKGROUND (clear window and
redraw background).
STEP 4:- PUT VALUE OF X CORDINATE (set the x coordinate
of the centre of the smiley face).
STEP 5:- PUT VALUE OF Y CORDINATE (set the y coordinate
of the centre of the smiley face).
STEP 6:- SET THE SMILEY FACE
STEP 7:- DRAW SMILEY FACE

3. LOOP
• WE HAVE TO APPLY LOOP BECAUSE WHEN WE
MAKE MOVEMENT OF SMILEY FACE THEN SOME
TYPE OF DISTURBANCE WILL BE GENERATED IN
THE BACKGROUND.

4. DRAW BACKGROUND
• STEP 1:- DRAW BACKGROUND (clear window and redraw
background).
• STEP 2 :- X=X+1 (here this representation is used for moving smiley
face).
• STEP 3 :- DRAW SMILEY (redraw the smiley face).
• STEP 4 :- UPGRADE GRAPH WINDOW (show completed image ).
• STEP 5 :- MOVE BUTTON PRESSED (left button)
• STEP 6 :- CLOSE GRAPH WINDOW.

5. OPENING OF WINDOW
• STEP 1 :- START
• STEP 2 :- OPEN_GRAPH_WINDOW(400,300),
• STEP 3 :- SET_WINDOW_TITLE (“SMILEY”)
• STEP 4 :- CLEAR_WINDOW (basically graph window sets the title and sets the background color
to
light cyan).
• STEP 5 :- [LIGHT_CYAN]
• STEP 6 :- FREEZE_GRAPH_WINDOW
• STEP 7 :- END

6. LOOP
• THE TWO SUBCHARTS ONLY MOVE EACH OBJECT
ONE STEP.
• THE REPEATED CALLS TO MOVE AND DRAW IN THE
LOOP IS WHAT ACTUALLY PRODUCES THE MOMENT.

7. DRAW AND MOVE TWO BALLS BY INITIALIZING
COORDINATES AFTER OPENING WINDOW
• STEP 1 :- START
• STEP 2 :- OPEN_WINDOW
• STEP 3 :- INITIAL CORDINATES
• BEFORE COMING TO STEP 4 FOR DRAWING BACKGROUND WE HAVE TO DO
LOOP PART AGAIN FOR THIS NEW ANIMATION.

8. DRAW BACKGROUND ND CIRCLE FOR THE
MOMENT OF TWO BALLS
• CONTINUE:-----
• STEP 4 :- DRAW BACKGROUND (clearing the window and redraw window).
• STEP 5 :- MOVE_GREEN_BALL
• STEP 6 :- DRAW CIRCLE (green_x_green_y)0.Green,True).
• STEP 7 :- MOVE RED_RED_BALL
• STEP 8 :- DRAW CIRCLE (red_x,red_y,20.Red,True).
• STEP 9 :- UPGRADE_GRAPH_WINDOW
• STEP 10 :- MOVE_BUTTON_PRESSED(left_button).

9. MOVEMENT OF GREEN BALL
STEP 1 :- START
STEP 2 :- GREEN_X implies GREEN_X + GREEN_DELTA_X(this step is used
for set the coordinates of x according to given color).
AFTER NEXT STEP WE WILL SEE THE CHANGES IN X COORDINATES OF
GREEN BALL
STEP 3 :-GREEN_X<10 OR GREEN_X>390
STEP 4 :- GREEN_X implies GREEN_DELTA_X[-1](here subtraction means
ball will go in opposite direction through x cordinate).
STEP 5 :-GREEN_Y implies GREEN_Y+GREEN_DELTA_Y
STEP 6 :-GREEN_Y<10 OR GREEN_Y>290
STEP 7 :- GREEN_Y implies GREEN__DELTA_Y[-1](here same subtraction
will move ball in opposite direction through y coordinate).
STEP 8 :- TIME TAKEN AS ZERO.
STEP 9 :-END

10. MOVEMENT OF RED BALL
STEP 1:- START
SAME PROCESS WE HAVE TO APPLY OR DEAL WITH THIS BALL ALSO.
STEP 2 :-TIME=TIME+1
STEP 3 :-RED_X implies SIN(time*pi/180)*100+200
STEP 4 :-RED_Y implies COS(time*pi/180)*100 implies 150.
STEP 5 :- END

11. Animation Is One Of The Best,
interesting And Attractive Part
To Do In Raptor.
THANK YOU FOR WATCHING THIS.
