Dynamic in-game object creation and manipulation

[Tomi]

please post your code for how you setup the array of bullets

I'm using fixed length arrays:

bullets: array [0..100] of TBullet;

Then in a Timer event I create, move and destroy the bullets:

if (plshoot=true) and (plcanshoot=true) then
  begin
         abullet:=TBullet.create(Player.Left,Player.Top,bulletpic);
         bullets[numofbullets]:=abullet;
         inc(numofbullets);
  end;


  if numofbullets>=1 then
  begin
       for i:=0 to numofbullets-1 do
       begin
        if bullets[i]<>nil then
        begin
            bullets[i].yplace:=bullets[i].yplace-4;
            if bullets[i].yplace<10 then
            begin
                 freeandnil(bullets[i]);
                 if i=numofbullets-1 then
                    dec(numofbullets)
                 else
                 begin
                      for j:=i+1 to numofbullets-1 do
                          bullets[j-1]:=bullets[j];
                      dec(numofbullets);
                 end;
            end;
        end;
       end;
  end;

(I have already corrected the first variable of the loops from 1 to 0, as you wrote.)
When I press the fire button, the bullets are only flash at the top of the player. :-/
