Suppose you have 3 image components on your form, named Image1, Image2 and Image3. At design time, load an image in each of them via the Object Inspector (property "Picture").
Suppose you have 5 image files in the application's directory, named slot0.jpg, slot1.jpg,... slot4.jpg.
Suppose a button "Button1" that makes the slot wheels spin. You need 3 global variables for remembering the wheel positions, say No1, No2 and No3; these are used to load one of five different images into each Image component, and afterwards for the procedure that calculates the score.
var No1, No2, No3, Score, ScoreTotal: integer; procedure TForm1.Button1Click(Sender: TObject); var BaseName: string; begin BaseName := 'C:\SlotMachine\Slot'; // or whatever ;) Randomize; // randomize the random-generator No1 := Random(5); // first random number 0-4 No2 := Random(5); // second random number 0-4 No3 := Random(5); // third random number 0-4 Image1.Picture.LoadFromFile(BaseName + IntToStr(No1) + '.jpg'); Image2.Picture.LoadFromFile(BaseName + IntToStr(No2) + '.jpg'); Image3.Picture.LoadFromFile(BaseName + IntToStr(No3) + '.jpg'); DoScoring; end; procedure TForm1.DoScoring; begin // Calculate score and total score... // Display score... // and so on... end;
