ES 为 AE Script 添加一个 in 和 out 缓动值

Question

这是我第一次提出问题，而不仅仅是随机搜索。提前原谅我，在 JS 和 ES 方面，我比绿色更环保。

我正在尝试对我在这里找到的代码进行逆向工程：For loop in Adobe ExtendScript

它工作得很好，但它只允许我在关键帧的内外插入一个关键帧缓动值。我希望能够将它们分开，这样我就可以使用ease1 和ease2 而不仅仅是ease1。任何帮助将不胜感激！

function storeKeyframes(){
    var comp = app.project.activeItem;
    if (!comp || comp.typeName !== "Composition") return;
    var properties = comp.selectedProperties;
    var i, I=properties.length;
    var ease1 = new KeyframeEase(0,30);
    var ease2 = new KeyframeEase(0,45);

    for (i=0; i<I; i++){
        if (properties[i] instanceof Property) setEase(properties[i], ease1);
        };
    };
function setEase(property, ease1){
    var ease = property.propertyValueType===PropertyValueType.Two_D ? [ease1, ease1] : (property.propertyValueType===PropertyValueType.Three_D ? [ease1, ease1, ease1] : [ease1]);
    var keySelection = property.selectedKeys;
    var i, I=keySelection.length;
    for (i=0; i<I; i++){
        property.setInterpolationTypeAtKey(keySelection[i], KeyframeInterpolationType.BEZIER, KeyframeInterpolationType.BEZIER);
        property.setTemporalEaseAtKey(keySelection[i], ease, ease);
        };
    };

我相信这可能是你所追求的：

function storeKeyframes(){
    var comp = app.project.activeItem;
    if (!comp || comp.typeName !== "Composition") return;
    var properties = comp.selectedProperties;
    var numProps = properties.length;
    var ease1 = new KeyframeEase(0,30);
    var ease2 = new KeyframeEase(0,45);

    for (var i = 0; i < numProps; i++){
        if (properties[i] instanceof Property) setEase(properties[i], ease1, ease2 );
    };
};

function newSetEase( prop, inEase, outEase ) {
    var keySelection = prop.selectedKeys;
    var numKeys = keySelection.length;

    for(var i = 0; i < numKeys; i++) {
        prop.setInterpolationTypeAtKey(keySelection[i], KeyframeInterpolationType.BEZIER, KeyframeInterpolationType.BEZIER);

        if (!prop.isSpatial && prop.value.length == 3) {
            prop.setTemporalEaseAtKey(keySelection[i],[inEase,inEase,inEase],[outEase,outEase,outEase]);
        }
        else if (!prop.isSpatial && prop.value.length == 2) {
            prop.setTemporalEaseAtKey(keySelection[i],[inEase,inEase],[outEase,outEase]);
        }
        else {
            prop.setTemporalEaseAtKey(keySelection[i],[inEase],[outEase]);
        }
    }
}

storeKeyframes()
