BlockCraft
This app lets you draw on the screen to make cool 3D effects. Dragging on the screen draws with hundreds of little cubes. Tapping a cube makes it pop and disappear.
1 function drag() {
Line 1 creates a new block of code called drag() which tells the app what to do when you drag your cursor on the screen.
- The drag() function is built into Bitsbox.
- A function is a block of code which only runs when it's called. In this case, the drag() function is called whenever someone drags on the screen.
2 ink = stamp('cube3',x,y,75)
Line 2 puts a blue cube on the screen and assigns it the name "ink". The cube appears precisely where your cursor is touching the screen.
- 'cube3' is the label of the cube graphic we want the app to use.
- x and y refer to where you're touching on the screen.
- 75 is the size of the cube on the screen, in pixels.
3 ink.tap = pop
Line 3 tells "ink" (which is the cube) to pop when it's tapped.
- The pop function is built into Bitsbox.
4 }
Line 4 uses a curly bracket } to indicate that this is the end of the drag() function which started on line 1.
5 fill('grid2')
Line 5 puts a background image of graph paper on the screen.
- 'grid2' is the label of the graphic we want the app to use.
