Post subject: | Paddle And Ball Collision Help |
PLEASE can someone HELP ME....This is my THIRD topic about this subject and no one has answered my question. question : " How can i get my pong ball to bounce off the paddle????" i already have it set up to if it misses the paddle, (ie, hits bottom edge) the program finishes, and i have it that that ball bounces off of my borders but i cannot figure out how to make the ball bounce off the paddle. Someone said that it is the same code that i used to the borders, but ive tried different combinations like about 100 times... plz someone answer my question here is my code drawfill (1, 399, 150, 150) % Ball is slding across title var font1 : int %defiing font as an integer font1 := Font.New ("Stencil:30") % defining font size assert font1 > 0 Font.Draw ("Greg's Ping Pong Game", 160, 325, font1, red) % Main Title Font.Free (font1) colorback (6) % the background color locate (7, 30) var title1 : int %defines title1 as an integer title1 := 10 loop %begins title loop %Title wiper drawfilloval (title1, 335, 20, 20, 12) exit when title1 = 600 delay (50)%delay's playback 50 milliseconds drawfilloval (title1, 335, 20, 20, 158) % draws circle and fills it title1 := title1 + 10 end loop %ends title loop cls % clears the screen colorback (12)% defining background color put " ---The intructions are ---- " % outputs "Intructions" put " "% skips a line put " Move the Paddle with mouse " % outputs actual instructions put " Each time you keep the ball up in the air you reieve a point"% outputs actual instructions put " If you miss the ball, you lose "% outputs actual instructions put " "% skips a line put " "% skips a line put " "% skips a line put " "% skips a line put " "% skips a line % press any key to continue font1 := Font.New ("Stencil:20")%defines font1 as font.new and font size Font.Draw ("~~Press any Key to Begin~~", 90, 125, font1, red) Input.Pause % won't continue until user presses a key colourback (blue)% defining bacground color cls % Clears the screen setscreen ("offscreenonly") var rise, run, rad, u, yy, xx : int%defiing rise,run,rad,yy,xx as integers var bally, ballx : int := 200% defining bally,ballx as integers rad := 10 %defines Radius of ball rise := 2% defines where the ball starts run := 2 % defines where the ball starts loop%begins main loop var x, y, button : int %defines x,y,button as integers Mouse.Where (x, y, button)%indicates where the mouse is Draw.FillOval (ballx, bally, rad, rad, yellow)% draws pong ball ballx := ballx + run bally := bally + rise if ballx + 50 >= maxx then run := -1 elsif ballx - 50 <= 0 then run := +1 elsif bally + 50 >= maxy then rise := -1 elsif bally - 50 <= 0 then exit end if View.Update delay (10) % delay's playback 10 milliseconds cls %Clears the screen % Paddle Draw.Box (50, 50, maxx - 50, maxy - 50, white)%draws main border drawfill (50, 40, white, white)% draws inside-outise white box drawfillbox (x - 80, 66, x + 80, 75, brightcyan) % Draws paddle % outside rectangle + fill drawline (40, 30, 40, 370, black)% draws line drawline (40, 30, 600, 30, black)% draws line drawline (600, 30, 600, 370, black)% draws line drawline (600, 370, 40, 370, black)% draws line drawfill (0, 10, brightred, black)%fills outside border brightred end loop % ends the main loop |

question : " How can i get my pong ball to bounce off the paddle????" I probably could start by being patient and not making new topics everytime i feel ignored.... i already have it set up to if it misses the paddle, (ie, hits bottom edge) the program finishes, and i have it that that ball bounces off of my borders but i cannot figure out how to make the ball bounce off the paddle. Someone said that it is the same code that i used to the borders, but ive tried different combinations like about 100 times... plz someone answer my question here is my code

Exactly. For this reason this topic will be locked. You're not just going to get the answer on a silver platter here. Tony has already given you more than enough information to do this in your other thread. |
