Sorry guys for all the questions, but im running this code, its taken from the spring example Do u know what do i need to change to make the text spring up and down, or left to right cause at the moment when i run it its going in a diagonal fashion.... Thanks guys... (also if i change the size it doesnt work at all...) import processing.core.*; import processing.app.*; import processing.core.PApplet; public class effects1 extends PApplet { // Spring drawing constants for top bar int s_height = 16; // Height int left = 50; // Left position int right = 150; // Right position int max = 150; // Maximum Y value int min = 20; // Minimum Y value boolean over = false; // If mouse over boolean move = false; // If mouse down and over // Spring simulation constants float mass = 2.8; // Mass float K = 0.2; // Spring constant float damping = 0.92; // Damping float R = 60; // Rest position // Spring simulation variables float position = 60.0; // Position float velocity = 0.0; // Velocity float acceleration = 5; // Acceleration float force = 0; // Force PFont font; public void setup() { size(200, 200, JAVA2D); //noStroke(); frameRate(60); font = loadFont("data/Tahoma-48.vlw"); } public void draw() { background(102); updateSpring(); drawSpring(); } public void drawSpring() { // Draw base fill(20); float b_width = 0.5 * position + -8; //rect(width/2 - b_width, ps + s_height, width/2 + b_width, 150); // Set color and draw top bar if(over || move) { fill(0); } else { fill(255); } textFont(font); text("String",width/2 - b_width, position + s_height); //rect(left, position, right, position + s_height); } public void updateSpring() { // Update the spring position if(!move) { force = -K * (position - R); // force=-ky acceleration = force / mass; // Set the acceleration, force=ma == acceleration=force/m velocity = damping * (velocity + acceleration); // Set the velocity position = position + velocity; // Updated position } if(abs(velocity) < 0.1) { velocity = 0.0; } // Test if mouse is over the top bar if(mouseX > left && mouseX < right && mouseY > position && mouseY < position + s_height) { over = true; } else { over = false; } // Set and constrain the position of top bar if(move) { position = mouseY - s_height/2; if (position < min) { position = min; } if (position > max) { position = max; } } } void mousePressed() { if(over) { move = true; } } void mouseReleased() { move = false; } }
