| 41 | 7 * |
| 117 | 8 * Animation is a program to move, resize, rotate, ..., changing |
| 9 * graphics on the output screen. | |
| 10 * | |
| 11 * \image html program.png | |
| 12 * | |
| 41 | 13 * XXX: Program is a sequence of actions duration a perior. |
| 14 * Actions are grouped into words. A program defines | |
| 15 * the order and time of playing of words. A word | |
| 16 * defines how long to perform a set of actions. Actions | |
| 17 * in a word are performed concurrently. | |
| 45 | 18 * |
| 19 * Animation shapes are updated periodically. Every action | |
| 20 * are working with start, step, and stop 3 calls. start is | |
| 21 * called when start time the word, contain it, due. step is | |
| 22 * called periodically in duration of playing time start at | |
| 23 * 'start time'. When the clock run out the playing time of | |
| 24 * a word, it call stop of actions in the word. | |
| 111 | 25 * |
| 26 * A program is driven by a timer. Once a program is started, it registers | |
| 27 * with timer for periodic running. \ref mb_tman_t is timer of | |
| 28 * MadButterfly. The update frequence is 10fps by default, now. | |
| 29 * | |
| 117 | 30 * \section use_progm How to Use Animation Program? |
| 31 * Following code block creates a program with 2 words. First word is | |
| 32 * started immediately after the program been started. It is consisted | |
| 33 * for 1 second. Second word is started 1 second after the program been | |
| 34 * started. It is consisted for 2 seconds. There are 2 action in | |
| 35 * first word, they shift graphics managed by coord1 & coord2 by (50,50) and | |
| 36 * (-50,50) pixels, respectly. The shifting is performed incrementally | |
| 37 * in 1 second. Second word shifts coord1 and coord2, too. And, graphics | |
| 38 * managed by coord3 are hidden at end of the word. At end of code in the | |
| 39 * block, mb_progm_start() starts the program. 3rd argument of | |
| 40 * mb_progm_start() must be current wall time. | |
| 41 * | |
| 42 * \code | |
| 43 * progm = mb_progm_new(10, &rdman); | |
| 44 * | |
| 45 * MB_TIMEVAL_SET(&start, 0, 0); | |
| 46 * MB_TIMEVAL_SET(&playing, 1, 0); | |
| 47 * word = mb_progm_next_word(progm, &start, &playing); | |
| 48 * | |
| 49 * act = mb_shift_new(50, 50, coord1, word); | |
| 50 * act = mb_shift_new(-50, 50, coord2, word); | |
| 51 * | |
| 52 * MB_TIMEVAL_SET(&start, 1, 0); | |
| 53 * MB_TIMEVAL_SET(&playing, 2, 0); | |
