Question - preloading motions

Rus · December 2015

I wonder if there is a way to pre-load mtns.


load_motion(motion1.mtn);
...
load_motion(motion2.mtn);
...
load_motion(motion1.mtn);


function load_motion(mtn){
	Figure.loadBytes(mtn, function(buf){
		motion = new Live2DMotion.loadMotion(buf);
	});	
}

Very frequently, I load motion1, then soon motion2, and soon after motion1 again.

The above code is making my game run slow on some devices. There isn't a lot of mtns. I need to interchange mtns frequently.
So I want to ask : How do I preload mtns?

PS: I tried to make an array (which would store all the motion bytes), for loop and this: motion[i] = new Live2DMotion.loadMotion(buf); . But it doesn't work.

Thank you in advance

Actually my pre-loading method using arrays suddenly worked. I must have made a trivial mistake in my code somewhere. Thank you anyways

And for anyone who want's to know how I did mtn preloading, here's how:

Near the very beginning, just after the .model.json is defined into your code:


for(var i = 0; i < modelDef.motion.length; i++){
	load_motion(modelDef.motion[i], i);
}


var init_mtn = 0;
var curr_mtn = init_mtn;

...

function load_motion(mtn, index){
	Figure.loadBytes(mtn, function(buf){
		motion = new Live2DMotion.loadMotion(buf);
		motion.setFadeIn(0);
		motion.setFadeOut(0);	
		motion_bytes[index] = motion;
		if(index === modelDef.motion.length-1){
			startMtn(curr_mtn);
		}		
	});		
}


function startMtn(no){
	motionMgr.startMotion(motion_bytes[no]);
}

And in the periodic draw function:


if(motionMgr.isFinished()){
	motionMgr.startMotion(motion_bytes[curr_mtn]);
}
motionMgr.updateParam(live2DModel);

I see. Thank you for sharing the information .
