Speed up DemoTransition One #12

Closed MattFoley closed 11 years ago

MattFoley commented 11 years ago

Is it possible to speed up DemoTransition one, or set a length of time? With a 100kb image, it usually takes a second or two to finish the transition on device, even on an iPhone 5. I'd like it to be closer to .5s.

If it's the falling block demo I tested this little tweak, from line 128 in DemoTransition.m

    if (moved<4) {
        int num = 2;
        if (rand()%100 > 50) {
            while (1) { // naïve loop to find a none moving square
                i = rand()%4;
                if (!(dyOut[i][j] > 0.0)) {
                    dyOut[i][j] = 0.02;
                    if (!--num)
                        break; // got one, leave now
                }
            }
        }
        break; // no more moving squares, leave outer loop
    }

this is initiate falling of two blocks and not only one at a time, which makes it run faster.

Hope that helps.
