Text Manipulation III: A Banner This little trick takes a string of letters and prints it, one letter at a time. It declares a variable within the string section of a Text node: Text1 = Text(720, 486, 1, {{ string logo = "My Logo Here"; stringf("%c", logo[(int) clamp(time-1, 0,strlen(logo))]) }}, "Courier", 100, xFontScale, 1, width/2, height/2, 0, 2, 2, 1, 1, 1, 1, 0, 0, 0, 45); This uses strlen to determine the length of the string and extract the letter that corresponds to the current frame. Text Manipulation IV: Text With a Loop to Make a Clock Face This eager little example lays out a clock face. A for loop is used to count from 1 to 12, and prints the number into a Text function with a stringf function. (You should just be able to print the value of count with {count}, but it doesn't work. Go figure.) The cosd and sind functions are also used to calculate the position of the number on the clock face. Keep in mind that zero degrees in Shake points east, as it does in all Cartesian math. The falloffRadius serves no purpose in the function except to complete the onscreen control set to give a center and a radius widget: image Clock( image In=0, float xCenter=width/2, float yCenter=height/2, float radius=150, float falloffRadius=0 ) { NumComp=Black(In.width,In.height,1); for (int count=1;count
