我是Processing的新手,我想在AndroID模式下运行我的草图.我希望它同时支持多个触摸.
我想知道是否有人可以指导我这个问题:
如何让草图支持多次触摸?
解决方法:
这是一个完整的例子:
/* * * androIDMultitouch.pde * Shows the basic use of Multitouch Events * *///-----------------------------------------------------------------------------------------// importSimport androID.vIEw.MotionEvent;//-----------------------------------------------------------------------------------------// VARIABLESint touchEvents;float xtouch[];float ytouch[];int currentPointerID = 0;boolean printFPS;//-----------------------------------------------------------------------------------------voID setup() { size(displayWIDth, displayHeight); orIEntation(LANDSCAPE); background(0, 255, 0); fill(0, 0, 244); rect(100, 100, 100, 100); stroke(255); // Initialize Multitouch x y arrays xtouch = new float [10]; ytouch = new float [10]; // Don't use more than ten fingers!}//-----------------------------------------------------------------------------------------voID draw() { background(255, 0, 0); for (int i = 0; i < xtouch.length; i++) { ellipse(xtouch[i], ytouch[i], 150, 150); }}//-----------------------------------------------------------------------------------------public boolean surfacetouchEvent(MotionEvent event) { // Number of places on the screen being touched: touchEvents = event.getPointerCount(); // If no action is happening, Listen for new events else for (int i = 0; i < touchEvents; i++) { int pointerID = event.getPointerID(i); xtouch[pointerID] = event.getX(i); ytouch[pointerID] = event.getY(i); float siz = event.getSize(i); } // ACTION_DOWN if (event.getActionMasked() == 0 ) { print("Initial action detected. (ACTION_DOWN)"); print("Action index: " +str(event.getActionIndex())); } // ACTION_UP else if (event.getActionMasked() == 1) { print("ACTION_UP"); print("Action index: " +str(event.getActionIndex())); } // ACTION_POINTER_DOWN else if (event.getActionMasked() == 5) { print("Secondary pointer detected: ACTION_POINTER_DOWN"); print("Action index: " +str(event.getActionIndex())); } // ACTION_POINTER_UP else if (event.getActionMasked() == 6) { print("ACTION_POINTER_UP"); print("Action index: " +str(event.getActionIndex())); } // else if (event.getActionMasked() == 4) { } // If you want the variables for motionX/motionY, mouseX/mouseY etc. // to work properly, you'll need to call super.surfacetouchEvent(). return super.surfacetouchEvent(event);}
