Random transitions

Using JavaScript with Hype
1

I’ve been poking about with this today and in my head it works but currently it does nothing. My javaScript is a bit adhock at best but I have the following code into a function when it fires it is meant to apply a random transition when moving to the next scene. I have jquery included in my project for the random

var trans_type=["hypeDocument.kSceneTransitionInstant",
  				"hypeDocument.kSceneTransitionCrossfade",
				"hypeDocument.kSceneTransitionSwap",
				"hypeDocument.kSceneTransitionPushLeftToRight",
			    "hypeDocument.kSceneTransitionPushRightToLeft",
				"hypeDocument.kSceneTransitionPushBottomToTop",
				"hypeDocument.kSceneTransitionPushTopToBottom"]

var trans = Math.floor(Math.random() * trans_type.length);
var picked = trans_type[trans];

hypeDocument.showNextScene(picked,0.8);

I solved this, thanks anyway. The issue was that you cannot use a variable name instead of the transition which makes the whole random from an array thing pointless.
here is what I went with should anyone need it in the future

> var trans = Math.floor(Math.random() * 7); 
> switch(trans) {
> case 0:
> 	hypeDocument.showNextScene(hypeDocument.kSceneTransitionInstant);
> 	break;
> case 1:
> 	hypeDocument.showNextScene(hypeDocument.kSceneTransitionCrossfade);
> 	break;
> case 2:
> 	hypeDocument.showNextScene(hypeDocument.kSceneTransitionSwap);
> 	break;
> case 3:
> 	hypeDocument.showNextScene(hypeDocument.kSceneTransitionPushLeftToRight);
> 	break;
> case 4:
> 	hypeDocument.showNextScene(hypeDocument.kSceneTransitionPushRightToLeft);
> 	break;
> case 5:
> 	hypeDocument.showNextScene(hypeDocument.kSceneTransitionPushBottomToTop);
> 	break;
> case 6:
> 	hypeDocument.showNextScene(hypeDocument.kSceneTransitionPushTopToBottom);
> 	break;
> default:
> 	hypeDocument.showNextScene(hypeDocument.kSceneTransitionSwap);
> 	}

Your original code is fine but you have created strings and the transitions are actually built in variables :slight_smile: so write your array like this:

var trans_type=[hypeDocument.kSceneTransitionInstant,
  				hypeDocument.kSceneTransitionCrossfade,
				hypeDocument.kSceneTransitionSwap,
				hypeDocument.kSceneTransitionPushLeftToRight,
			    hypeDocument.kSceneTransitionPushRightToLeft,
				hypeDocument.kSceneTransitionPushBottomToTop,
				hypeDocument.kSceneTransitionPushTopToBottom]
