squarefeet / SineArcJumping.js
Created February 28, 2012 23:46
Sine arc jumping. This chunk of code is called on each update tick, and with each tick, the position vector is moved along the sine curve...
// If jump key is pressed, toggle the isJumping property, reset the
// jumpSinPos to zero, and set the y position.
if(keyHandler.isKeyPressed('space') && !this.isJumping) {
this.vel.y = 0;
this.jumpSinPos = 0;
this.isJumping = true;
this.jumpStartPos = this.pos.y;
}
// If we're jumping, move along the sine wave.
