Processing 初體驗 - 結合Android手機

Processing 互動程式初體驗 - 1. 手指頭接觸點會有一個白色小圓圈, 畫面中的正方形會隨著手指頭移動而旋轉。 boxRotation += (float)(pmouseX - mouseX)/100; rotate(boxRotation); rect(0, 0, 150, 150); 2. 觸碰點與畫面中心連線, line(width/2, height/2, mouseX, mouseY); 3.背景顏色也會隨著坐標而改變 background(mouseX * (255.0/800), mouseY * (255.0/280), 0); 要轉換到Android上執行只要切換到Android mode就好了, 電腦上必須要有Android SDK, 並裝好您Android手機的driver就可以了。 相當輕鬆。 ================================================================ float boxRotation = 0; void setup(){ size(480, 800); smooth(); stroke(255); fill(255); rectMode(CENTER); }; void draw(){ background(mouseX * (255.0/800), mouseY * (255.0/280), 0); boxRotation += (float)(pmouseX - mouseX)/100; line(width/2, height/2, mouseX, mouseY); ellipse(mouseX, mouseY, 40, 40); pushMatrix(); translate(width/2, height/2); rotate(boxRotation); rect(0, 0, 150, 150); popMatrix(); };
