Overview
To demonstrate how to animate picture in LabVIEW
Description:
hen trying to create an animated 2D image in LabVIEW, I quickly realized the importance of modularity the program would require. I wanted to animate a character that could walk and stand still. I thought I could just jump to particular frames of the animation; however I then realized how these same functions could be repeated but for different sprites, whenever they're called, and then what would happen if I added more actions...
I'd eventually have to write in every frame value for each action. Instead I came up with the following idea I decided to keep each different 'reel' of frames in a separate folder. Then, by only using an enumerated type definition to refer to each folder's name (The sprite's name), the different sets of frames could be navigated with ease. Above, I grab the VI's path, strip it so I can later build paths to the different reels. By providing the name for the Sprite (This is used as the folder directory name for all of the specified different reels) , the different frame sets can be referenced in code. (Therefore to add a new sprite, you'd add a folder in the same directory called SpriteName with it's own respective frame folders). If all it did was bounce, you'd make a sub-directory called Bounce, and if it popped, a Pop directory. Then all that would be needed is an enum to
reference each of the animation folders and a call to the Sprite's name.
Hopefully this approach will be understandable in the block diagram.
