Hi,
I'm creating virtual tour of a house, the part I am working on at the moment involves a 360 spin view of the house (a series of 36 flat frames). Each corner of the house has a hotspot so that the user may click to navigate to that corner. I have completed the code to get the house to spin to the correct hotspot when the user clicks on a hotspot but where I'm struggling is working out the correct code so that if you are on position 1 and want to get to position 4 the house will spin backwards not forwards all the way through points 2 and 3 to get to 4.
Here is my code so far:
-
function loadPosition(frame,hotspots,callback) {
-
trace("-----------------------------------------------------------------");
-
sequence = mcSequenceContainer.sequence;
-
trace("1) loadPosition: "+frame+ " With hotspots: "+hotspots+" Current frame: "+sequence._currentframe);
-
-
sequence.onEnterFrame = function() {
-
-
// When final frame is reached stop play and load hotspots and or callback
-
if(this._currentframe == frame) {
-
trace("2) Final frame reached.");
-
if(hotspots != null) {
-
trace("3) Loading hotspots...");
-
loadHotspots(hotspots);
-
}
-
if(callback != null) {
-
trace("4) Callback not null");
-
callback();
-
}
-
this.stop();
-
delete this.onEnterFrame;
-
}
-
else {
-
// If frame is greater play sequence forwards
-
if(this._totalframes - frame >= frame + (this._totalframes - frame)) {
-
trace("Totalframes - frame: "+this._totalframes - frame+" Frame + totalframes - frame: "+frame + (this._totalframes - frame));
-
trace("Forwards: "+this._currentframe+" "+frame);
-
-
// Check currentframe doesn't exceed number of frames
-
if(this._currentframe + 1 > this._totalframes) {
-
// Reset to first frame and continue
-
this.gotoAndStop(1);
-
}
-
else {
-
// Increment frame
-
this.gotoAndStop(this._currentframe + 1);
-
}
-
-
}
-
-
// If frame is less than play sequence backwards
-
else if(this._totalframes - frame <= frame + (this._totalframes - frame)) {
-
trace("Totalframes - frame: "+(this._totalframes - frame)+" Frame + totalframes - frame: "+(frame + (this._totalframes - frame)));
-
trace("Backwards: "+this._currentframe+" "+frame);
-
-
// Ensure currentframe doesn't become a negative number
-
if(this._currentframe - 1 < 1) {
-
// Reset to first frame and continue
-
this.gotoAndStop(this._totalframes);
-
}
-
else {
-
// Decrement frame
-
this.gotoAndStop(this._currentframe - 1);
-
}
-
-
}
-
}
-
// DEV: trace("Current frame: "+sequence._currentframe+" Target frame: "+frame);
-
}
-
}
-
The code of interest is to the test statement, which im trying to get to work out how many frames it is in each direction to the target frame, then based on that result decide which direction to go:
-
if(this._totalframes - frame >= frame + (this._totalframes - frame))
-
Thanks,
Chromis
