向量线性插值

向量线性插值

任意值缓动
cc.misc.lerp(now,target,“比例”)；
pos.lerp(targetPos,“比例”)

 //相机跟随缓动
    lateUpdate() {
        let targetPos = cc.v2();
        targetPos.y = this.playerGroup.y + 400;
        //相机有一个最大移动范围在范围内移动
        if (this.playerGroup.x >= 0) {
            targetPos.x = this.playerGroup.x / 375 * 128;
        } else if (this.playerGroup.x < 0) {
            targetPos.x = -this.playerGroup.x / 375 * -128;
        };
        this.mainCamera.position = this.mainCamera.position.lerp(targetPos, 0.1);
    },
