Coding the Main Character

Once you have positioned all the different characters, you can start coding the game. You need to start with one activity after the other. Indeed, the code for the main game is obviously the more complicated, therefore you need to be organized and document the different elements you are using. Besides, you may test regularly your progress by compiling the game and executing it.

Let's start with the coding of the level 1 game and more precisely with the main character. You need again to play the game in order to understand the pattern of the character's movement along with any interaction with the other characters or surroundings.

Here is the code for moving the main character:
if (key=VK_RIGHT) and (Blocked=false) then begin // Key Right
if PosChar=2 then begin PosChar:=3; ImageMan3.visible:=true; ImageMan2.visible:=false; PlaySound(pfPlay); end;
if PosChar=1 then begin PosChar:=2; ImageMan2.visible:=true; ImageMan1.visible:=false; PlaySound(pfPlay); end;
if PosChar=5 then begin PosChar:=6; ImageMan6.visible:=true; ImageMan5.visible:=false; PlaySound(pfPlay); end;
if PosChar=4 then begin PosChar:=5; ImageMan5.visible:=true; ImageMan4.visible:=false; PlaySound(pfPlay); end;
if PosChar=8 then begin PosChar:=9; ImageMan9.visible:=true; ImageMan8.visible:=false; PlaySound(pfPlay); end;
if PosChar=7 then begin PosChar:=8; ImageMan8.visible:=true; ImageMan7.visible:=false; PlaySound(pfPlay); end;
end;
if (key=VK_LEFT) and (Blocked=false) then begin // Key Left
if PosChar=2 then begin PosChar:=1; ImageMan1.visible:=true; ImageMan2.visible:=false; PlaySound(pfPlay); end;
if PosChar=3 then begin PosChar:=2; ImageMan2.visible:=true; ImageMan3.visible:=false; PlaySound(pfPlay); end;
if PosChar=5 then begin PosChar:=4; ImageMan4.visible:=true; ImageMan5.visible:=false; PlaySound(pfPlay); end;
if PosChar=6 then begin PosChar:=5; ImageMan5.visible:=true; ImageMan6.visible:=false; PlaySound(pfPlay); end;
if PosChar=8 then begin PosChar:=7; ImageMan7.visible:=true; ImageMan8.visible:=false; PlaySound(pfPlay); end;
if PosChar=9 then begin PosChar:=8; ImageMan8.visible:=true; ImageMan9.visible:=false; PlaySound(pfPlay); end;
end;
if (key=VK_DOWN) and (Blocked=false) then begin // Key Down
if PosChar=4 then begin PosChar:=1; ImageMan1.visible:=true; ImageMan4.visible:=false; end;
if PosChar=7 then begin PosChar:=4; ImageMan4.visible:=true; ImageMan7.visible:=false; end;
if PosChar=5 then begin PosChar:=2; ImageMan2.visible:=true; ImageMan5.visible:=false; end;
if PosChar=8 then begin PosChar:=5; ImageMan5.visible:=true; ImageMan8.visible:=false; end;
if PosChar=6 then begin PosChar:=3; ImageMan3.visible:=true; ImageMan6.visible:=false; end;
if PosChar=9 then begin PosChar:=6; ImageMan6.visible:=true; ImageMan9.visible:=false; end;
if PosChar=10 then begin PosChar:=9; ImageMan9.visible:=true; ImageMan10.visible:=false; end;
end;
if (key=VK_UP) and (Blocked=false) then begin // Key Up
if ((PosChar=10) and (BombCPos<>2)) then begin PosChar:=11; ImageMan11.visible:=true; ImageMan10.visible:=false; end;
if PosChar=9 then begin PosChar:=10; ImageMan10.visible:=true; ImageMan9.visible:=false; Score:=Score+20; end;
if PosChar=4 then begin PosChar:=7; ImageMan7.visible:=true; ImageMan4.visible:=false; Score:=Score+20; end;
if PosChar=1 then begin PosChar:=4; ImageMan4.visible:=true; ImageMan1.visible:=false; Score:=Score+20; end;
if PosChar=5 then begin PosChar:=8; ImageMan8.visible:=true; ImageMan5.visible:=false; Score:=Score+20; end;
if PosChar=2 then begin PosChar:=5; ImageMan5.visible:=true; ImageMan2.visible:=false; Score:=Score+20; end;
if PosChar=6 then begin PosChar:=9; ImageMan9.visible:=true; ImageMan6.visible:=false; Score:=Score+20; end;
if PosChar=3 then begin PosChar:=6; ImageMan6.visible:=true; ImageMan3.visible:=false; Score:=Score+20; end;
if PosChar=0 then begin PosChar:=1; ImageMan1.visible:=true; ImageMan0.visible:=false; Score:=Score+20; end;
end;
