示例1: step
void CCMissile::step(float dt) {
// position of target and aimed
CCNode* target = getTarget();
CCPoint t = target->getPosition();
CCPoint a = m_aimed->getPosition();
// position vector degree
CCPoint v = ccpSub(a, t);
float r = ccpToAngle(v);
float d = -CC_RADIANS_TO_DEGREES(r);
d -= m_presetDegree;
// save dest degree
if(m_dstDegree != d) {
m_dstDegree = d;
}
// rotate to dst degree gradually
if(m_dstDegree > target->getRotation()) {
float cur = MIN(m_dstDegree, target->getRotation() + dt * ANGULAR_VELOCITY);
target->setRotation(cur);
} else if(m_dstDegree < target->getRotation()) {
float cur = MAX(m_dstDegree, target->getRotation() - dt * ANGULAR_VELOCITY);
target->setRotation(cur);
}
// move target by velocity
float move = m_velocity * dt;
float distance = ccpLength(v);
if(move >= distance) {
target->setPosition(a);
} else {
t.x += move * cosf(r);
t.y += move * sinf(r);

}
// is done?
m_done = getTarget()->getPositionX() == m_aimed->getPositionX() &&
getTarget()->getPositionY() == m_aimed->getPositionY();
// done callback
