This section explains how to create a compound sound effect from elementary sounds. In the first example (two macros), the sound is played in a loop which is a native internal loop within the “PlaySound” function (using the flag option: SND_LOOP = &H8). A second function (the “Beep” function) creates a tone generator with adjustable frequency and play time. The Beep functionContinue Reading

In this part of the tutorial, the analysis of the ball movement is continued. The effects of the collision events are introduced in the equations of movement.

In this section two bats are created (the opponent’s bat and the player’s bat). The player’s bat movements are controlled by the vertical mouse movement. The geometry of movement, placement and charting of the bats are explained.

This post contains the first part of a series of tutorials demonstrating how to build a lively game of Pong in Excel. The section deals with the bat movement VBA macro, and plotting the “court” or “tennis-table”  on a 2D scatter chart.

Most of the models on this blog are designed for Excel 2003 or earlier versions. Sometimes however, Excel 2007 or 2010 are the only versions available even though they might be far slower when running these models. This presentation is an introduction to Excel 2007 and it was suggested to me by one of my readers. [sociallocker] [/sociallocker] Creating, Sizing,Continue Reading

Hi guys, by popular demand, this is a file containing five different animated speedometers and a tachometer (rpm-meter). I can recognize two models: a Toyota Camry and a Ford Crown Victoria. They work great. The rest I am not sure what they are, I would appreciate if you tell me. Just leave a comment. The model works in all versions of Excel. Cheers, GeorgeContinue Reading

Hello everyone, this is a tutorial in which a virtual  Excel joystick controlled by mouse movements on a scatter chart has been demonstrated . While in operation, a macro updates the coordinates of the pointer in two spreadsheet cells. The two coordinates are then incorporated in formulas which limit the range of motion of the joystick. Just like a realContinue Reading

Hi Folks, there are many available built-in spreadsheet functions in Excel. Ocasionaly one might need to write a special custom function. This second short tutorial is an introduction to that. Creating a “Time Stamp” function is presented as a first example after which a concatenation function between a custom formatted date and a string (text) is introduced. This last function came about fromContinue Reading

There are many available built-in spreadsheet functions in Excel. Occasionally one might need a very special custom function. This short tutorial is an introduction about how to write a user defined function which calculate the distance between two points in a Cartesian plane. The topic will be continued and custom functions will occasionally be used in future models. We’d loveContinue Reading

Hi guys, here is the final part of tutorial about creating a digital clock in Excel. It is a good tutorial about general use of sprites in animation, especially the first half. Tell us your thoughts, George [sociallocker][/sociallocker] Building an Digital Clock in Excel – part #2 – a full digital clock model using the “digit” sprites by George LunguContinue Reading
