I wrote a script to use as a launch animation that scales an item up and then down again (kinda like a bounce).
function fillOptions(options, defaults){
options = options || {};
for(var p in defaults){
if(typeof options[p] === “undefined”)
options[p] = defaults[p]
}
return options;
}
function setAndClearTimeout(func, timeout){
var id = setTimeout(function(){
clearTimeout(id);
func();
}, timeout);
}
function animScale(it, newScale, duration, options){
options = fillOptions(options, {animType: null, clearBindings: true});
var varName = “scaleAnim”;
var form = “animate(‘$”+varName+”‘, “+duration;
if(options.animType!==null)
form += ‘, “‘+options.animType+'”‘;
form += ‘)’;
var prop = it.getProperties();
var onGrid = prop.getBoolean(“i.onGrid”);
if(onGrid){
it.setBinding(“s.iconScale”, form, true)
}else{
it.setBinding(“t.sx”, form, true);
it.setBinding(“t.sy“, form, true)
}
LL.setVariableFloat(varName, newScale);
setAndClearTimeout(function after(){
if(options.preciseFinish){
if(onGrid){
prop.edit().setFloat(“s.iconScale”, newScale).commit()
}else{
it.setScale(newScale, newScale);
}
}
if(options.clearBindings){
if(onGrid){
it.unsetBinding(“s.iconScale”)
}else{
it.unsetBinding(“t.sx”);
it.unsetBinding(“t.sy“);
}
}
if(options.after){
options.after()
}
}, duration)
}
function bounce(it, duration, scaleIncrease, options){
options = fillOptions(options, {after: null});
var itProp = it.getProperties()
, itScale;
if(itProp.getBoolean(“i.onGrid”)){
itScale = itProp.getFloat(“s.iconScale”)
}else{
itScale = it.getScaleX()
}
animScale(it, itScale+scaleIncrease, duration/2, {animType:”de”, clearBindings:false, after: function(){
animScale(it, itScale, duration/2, {animType:”ac”, after: options.after, preciseFinish: true});
}});
}
var e = getEvent();
var it = e.getItem();
bounce(it, 100, 0.25, {after: function(){
setAndClearTimeout(function(){
if(it.getIntent().getAction() == “android.intent.action.MAIN”){
getActiveScreen().runAction(EventHandler.RUN_SCRIPT, it, getScriptByName(“Scaling Animation”).getId());
}else{
it.launch()
}
},0)
}});

i just use bindings on the items that I want to “bounce” … e.g.
Scale X set to
1 + $bounce*0.2*(animate(‘$ll_second’,500,”li”)%1)
where $bounce is a binary variable to toggle whether i want bouncing to occur
not sure if it uses a ton of battery, since i have nothing to compare it with …

But if you apply this on multiple items they will all bounce right? I only want the animation to occur when I tap an item.
As comparison you could just disable the binding and check LL battery usage right?

< ![CDATA[
yes, i have multiple items bouncing simultaneously. i don’t see a noticeable battery usage difference when the binding is off …
