Cocos Creator
1

Hello i’m new on Cocos Creator and also type script.

I’m trying to make array of class but i couldn’t done it. Because of the simple error down below.
[Scene] Cannot read property ‘constructor’ of undefined
[Scene] Value dump failed.

When i tried to change the values o editor it resets to 0.
The code is down below;

VideoControllerData.ts;

import { Vec2, _decorator } from 'cc';
const { ccclass, property } = _decorator;

@ccclass('VideoControllerData')
export class VideoControllerData {
    @property({ type: Number })
    targetTime: number = 0;

    @property({type: Vec2})
    targetPosition: Vec2;
}

VideoController.ts

import { _decorator, approx, Component, VideoPlayer } from 'cc';
const { ccclass, property } = _decorator;
import { VideoControllerData} from './VideoControllerData';

@ccclass('VideoController')
export class VideoController extends Component {
    @property({ type: [VideoControllerData] })
    videoControllerData: VideoControllerData[] = [];
}
2 
export class VideoControllerData {
    @property({ type: CCInteger })
    // @property(CCFloat)
    targetTime: number = 0;

    @property(Vec2)
    targetPosition = new Vec2();
}

Error’s are disappeared but still changes doesn’t effects the values.

For example if i put target time 1-2-3-4 etc. it resets to 0.
