Pong Remake (Player2's Paddle won't show)

-----------------------------------

Hey, recently I have been trying to recreate the game pong and ran into some trouble showing the second player. I was wondering if someone would be so kind as to tell me what I did wrong. Help is appreciated. 



Thanks in advance





%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%PLAYER1%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%

View.Set("offscreenonly")



colourback (7)          



var x1, y1 : int                       
x1 := 50                               
y1 := 100
var chars1 : array char of boolean
loop
    Input.KeyDown (chars1)            
    if chars1 ('w') then
        y1 := y1 + 5
    end if


    if chars1 ('s') then
        y1 := y1 - 5
    end if

    drawfillbox (x1 - 10, y1, x1 + 10, y1 + 100, gray)   
    delay (10)                          
View.Update 

 cls   

end loop
%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%PLAYER2%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%


var x2, y2 : int                    
x2 := 100                                 
y2 := 200
var chars2 : array char of boolean     
loop
    Input.KeyDown (chars2)            
    if chars2 ('8') then
        y2 := y2 + 5
    end if


    if chars2 ('5') then
        y2 := y2 - 5
    end if

    drawfillbox (x2 - 10, y2, x2 + 10, y2 + 100, gray)   
    delay (10)                          
View.Update 
  cls 

end loop

-----------------------------------

Since your loop for your player 1 loop is first, it stays in that loop and never reaches the second loop where player 2 is blitted onto the screen.

-----------------------------------

Use one major loop, and it will work fine, and you should see them clearly.

Thanks for replying.


I tried using one loop for both the player paddles, but the new problem is that it is very flickery, and player 2 barely moves until he pops back into his spawn location. here is the syntax




%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%PLAYER1%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%



View.Set("offscreenonly")



colourback (7)         



var x1, y1 : int                       
x1 := 50                               
y1 := 150
var chars1 : array char of boolean
loop
    Input.KeyDown (chars1)           
    if chars1 ('w') then
        y1 := y1 + 5
    end if


    if chars1 ('s') then
        y1 := y1 - 5
    end if

    drawfillbox (x1 - 10, y1, x1 + 10, y1 + 100, gray)   
    delay (10)                         
View.Update

 cls   


%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%PLAYER2%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%


var x2, y2 : int                   
x2 := 575                               
y2 := 150
var chars2 : array char of boolean     

    Input.KeyDown (chars2)           
    if chars2 ('o') then
        y2 := y2 + 5
    end if


    if chars2 ('l') then
        y2 := y2 - 5
    end if

    drawfillbox (x2 - 10, y2, x2 + 10, y2 + 100, gray)   
    delay (10)                         
View.Update
  cls

end loop

Re: Pong Remake (Player2's Paddle won't show)

-----------------------------------

You should take the variables for the second player out of the loop. 
Also to removce the flashing just remove the first cls and View.Update. 
Hope this helps.

You will need to set boundaries for your paddles, by checking it's y positions, just to ensure to doesn't float off the page.
