ADOBE DIRECTOR 11.0 860 Scripting Dictionary For best results, set a QuickTime cast member's mask property before any of its sprites appear on the Stage in the on beginSprite event handler. Setting or changing the mask property while the cast member is on the Stage can have unpredictable results (for example, the mask may appear as a freeze frame of the digital video at the moment the mask property took effect). Masking is an advanced feature; you may need to experiment to achieve your goal. This property can be tested and set. To remove a mask, set the mask property to 0. Example This frame script sets a mask for a QuickTime sprite before Director begins to draw the frame: -- Lingo syntax on prepareFrame member("Peeping Tom").mask = member("Keyhole") end // JavaScript syntax function prepareFrame() { member("Peeping Tom").mask = member("Keyhole"); } See also invertMask maxInteger Usage the maxInteger Description System property; returns the largest whole number that is supported by the system. On most personal computers, this is 2,147,483,647 (2 to the thirty-first power, minus 1). This property can be useful for initializing boundary variables before a loop or for limit testing. To use numbers larger than the range of addressable integers, use floating-point numbers instead. They aren't processed as quickly as integers, but they support a greater range of values. Example This statement generates a table, in the Message window, of the maximum decimal value that can be represented by a certain number of binary digits: on showMaxValues b = 31 v = the maxInteger repeat while v > 0 put b && "-" && v b = b-1 v = v/2 end repeat end
