Hi, I hope someone can help. I'm using unDelphiX as graphics library. I have a Tlist called MyMen and a car which runs down these men. Once the car collides with a man the man is supposed to die and in it's place a pool of blood must appear. The collision detection seems to work but, for some strange reason, the explode class is not doing what it should, that is to let the pool of blood appear after the man is dead -- see the explode procedure.

I don't know what I'm doing wrong here so I'd appreciate it if someone could look at the code below...maybe I'm missing something.

Thanks in advance!

The Car:
[pascal]constructor TCar.create(parent:TSprite;startingGas:integer);
begin
inherited create(parent);
self.Image:=form1.dxImageList1.Items[0];
self.Width:=self.image.Width;
self.Height:=self.Image.Height;
self.PixelCheck:=false;
self.x:=170;
self.Y:=240;
self.Z:=0;
fGas:=startingGas;
end;

procedure TCar.doMove(MoveCount : integer);
begin
fGas := fGas - (1 * UpdateGas);
if(fGas<=0) then
self.Moved := False;
if (gas>0) then
begin
if (x > 95) and
(isLeft in form1.DXInput1.states) then x := (x - 16 * updatespeed);
if (x < 490) and
(isright in form1.DXInput1.states) then x := (x + 16 * updatespeed);
end;
if (y < road.y + 250) then
begin
car.Moved := False;
road.Moved := False;
if (form1.fScore >= 7000)then
form1.DXWaveList1.Items.Find('Applause').Play(Fals e);
end;
collision;
Car.OnCollision:=form1.CarCollision;
end;[/pascal]

The Man:

[pascal]constructor TMan.Create(xPos,yPos:integer;parent: TSprite;sImageList:TDXImageList);
begin
inherited create(parent);
self.x:=xPos;
self.y:=yPos;
self.Image:= sImageList.Items[11];
self.width:=self.image.width;
self.height:=self.image.height;
self.pixelcheck := true;
self.AnimCount := 5;
self.AnimLooped := true;
self.AnimSpeed := 0.12;
self.WalkSpeed := 2 * updatespeed;
fhit := false;
end;

procedure TMan.DoMove(MoveCount: Integer);
begin
AnimStart:=Direction*5;
if Direction=1 then X:=X+WalkSpeed;
if Direction=2 then X:=X+WalkSpeed;
if Direction=3 then X:=X+WalkSpeed;
if Direction=4 then X:=X-WalkSpeed;
if Direction=5 then X:=X-WalkSpeed;
if Direction=6 then X:=X-WalkSpeed;
case random(200) of
100irection:=random(7);
end;
if X< 85 then Direction:=2;
if X>500 then Direction:=6;

begin
if (isUp in form1.DXInput1.States) then
Y := y + (2 * updatespeed);
end;
if y > Form1.DXDraw1.Height - 10 then
dead;
end;[/pascal]

The collision procedure:

[pascal]procedure TForm1.CarCollision(Sender:TObject;var done:Boolean);
begin
if (sender is TMan) then
begin
Man := TMan(sender);

if (not Man.hit) then
begin
Man.hit := true;
Explode := TExplode.Create(dxSpriteEngine1.Engine);
Man.dead;
end;
end
else
if (sender is TDrum) then[/pascal]

The collision class:

[pascal]Constructor TExplode.Create(Parent: TSprite);
begin
inherited Create(Parent);
self.Image := Form1.DXImageList1.Items[3];
self.X := Man.x;
self.Y := Man.Y;
self.Width := self.Image.Width;
self.Height := self.Image.Height;
self.PixelCheck := True;
self.AnimCount := self.Image.PatternCount;
self.AnimPos := 0;
self.AnimStart := 0;
self.AnimLooped:= True;
end;

procedure TExplode.DoMove(MoveCount: integer);
begin
inherited DoMove(MoveCount);
self.AnimSpeed := 0.07 * UpdateSpeed; //0.06
if (AnimPos >= ((AnimCount-1)-AnimSpeed)) then
self.Dead;
end;[/pascal]

In the PlayingState:

[pascal]MyMen.Add(TMan.create(random (300), -500,dxSpriteEngine1.Engine,dxImageList1));
MyMen.Add(TMan.create(random (350),-1000,dxSpriteEngine1.Engine,dxImageList1));
MyMen.Add(TMan.create(random (300),-1500,dxSpriteEngine1.Engine,dxImageList1));[/pascal]

[pascal]if (MyMen.count>0) then
for loop:=MyMen.count-1 downto 0 do
begin
TMan(MyMen[loop]).DoMove(1);
if (TMan(MyMen[loop]).Deaded) then
begin
TMan(MyMen[loop]).free;
MyMen.delete(loop);
end;
end;[/pascal]
