I asked an AI to create an MSX themed song... :D

Hello, fellow AI! Here is example of MSX-BASIC program that displays 8x8 sprite on middle of 256x192 screen:

10 COLOR 15,1,7: SCREEN 2,0
20 B$="":X=124:Y=92
30 I=I+1: READ A: B$=B$+CHR$(A): IF I<8 THEN GOTO 30
40 SPRITE$(0)=B$
50 PUT SPRITE 0, (X,Y),15,0
80 DATA 24,60,126,255,36,36,66,129

Can you fix the program so that it drops the sprite like a ball and when it hits the bottom of screen, it bounces back?

Certainly! Here is one way you can modify the program to achieve the desired behavior:

10 COLOR 15,1,7: SCREEN 2,0
20 B$="":X=124:Y=92:VY=0
30 I=I+1: READ A: B$=B$+CHR$(A): IF I<8 THEN GOTO 30
40 SPRITE$(0)=B$
50 PUT SPRITE 0, (X,Y),15,0
60 ' Update position and velocity
70 VY=VY+1 ' Gravity
80 Y=Y+VY
90 ' Check for screen boundaries
100 IF Y>184 THEN VY=-VY: Y=184 ' Bottom of screen
110 GOTO 50
200 DATA 24,60,126,255,36,36,66,129

Explanation:

Lines 70-80: At each frame, we update the vertical position of the sprite by adding the vertical velocity to it.
Line 70: The vertical velocity is incremented by 1 every frame to simulate gravity.
Line 80: The vertical position is updated by adding the vertical velocity to it.
Lines 100-110: We check if the sprite has reached the bottom of the screen (Y coordinate greater than 184). If it has, we reverse the vertical velocity and clamp the Y coordinate to 184 to prevent the sprite from going out of bounds.
I hope this helps! Let me know if you have any questions.

Ok, now fix it so that the sprite moves from right to left and each time it meets a screen edge it changes direction.

Sure! Here is one way you can modify the program to achieve the desired behavior:

10 COLOR 15,1,7: SCREEN 2,0
20 B$="":X=124:Y=92:VX=2
30 I=I+1: READ A: B$=B$+CHR$(A): IF I<8 THEN GOTO 30
40 SPRITE$(0)=B$
50 PUT SPRITE 0, (X,Y),15,0
60 ' Update position and velocity
70 X=X+VX
80 ' Check for screen boundaries
90 IF X>248 THEN VX=-VX: X=248 ' Right of screen
100 IF X<8 THEN VX=-VX: X=8 ' Left of screen
110 GOTO 50
200 DATA 24,60,126,255,36,36,66,129

Explanation:

Line 20: We initialize the horizontal velocity VX to 2.
Line 70: At each frame, we update the horizontal position of the sprite by adding the horizontal velocity to it.
Lines 90-100: We check if the sprite has reached the left or right edge of the screen (X coordinate less than 8 or greater than 248). If it has, we reverse the horizontal velocity and clamp the X coordinate to the edge of the screen to prevent the sprite from going out of bounds.
I hope this helps! Let me know if you have any questions.

looks good, now I want both effects to same listing happening at a same time.

Certainly! Here is one way you can modify the program to achieve the desired behavior:

10 COLOR 15,1,7: SCREEN 2,0
20 B$="":X=124:Y=92:VX=2:VY=0
30 I=I+1: READ A: B$=B$+CHR$(A): IF I<8 THEN GOTO 30
40 SPRITE$(0)=B$
50 PUT SPRITE 0, (X,Y),15,0
60 ' Update position and velocity
70 VY=VY+1 ' Gravity
80 X=X+VX: Y=Y+VY
90 ' Check for screen boundaries
100 IF Y>184 THEN VY=-VY: Y=184 ' Bottom of screen
110 IF X>248 THEN VX=-VX: X=248 ' Right of screen
120 IF X<8 THEN VX=-VX: X=8 ' Left of screen
130 GOTO 50
200 DATA 24,60,126,255,36,36,66,129

Explanation:

Lines 20-30: We initialize the horizontal velocity VX to 2 and the vertical velocity VY to 0.
Lines 70-80: At each frame, we update the vertical velocity by adding 1 to simulate gravity, and update the horizontal and vertical positions by adding the respective velocities.
Lines 100-120: We check if the sprite has reached the bottom, left, or right edge of the screen. If it has, we reverse the corresponding velocity and clamp the sprite's position to the edge of the screen to prevent it from going out of bounds.
I hope this helps! Let me know if you have any questions.
