cocos3.x 2d转3d

2d转3d方式

    private _touchEnd(touch: EventTouch) {
        const camera = this.camera3d.camera;
        let rolePos = new Vec3();
        let worldPos = this.roleNode.worldPosition;
        camera.worldToScreen(rolePos, worldPos);

        const touchPos = touch.getLocation();
        console.log(`touchPos: x=${touchPos.x}, y=${touchPos.y}`);
        //0。01为z轴；
        const screenPos = new Vec3(touchPos.x, touchPos.y, 0.01);
        camera.screenToWorld(rolePos, screenPos);

        const uiTrans = this.roleNode.parent.getComponent(UITransform);
        rolePos = uiTrans.convertToNodeSpaceAR(rolePos);
        this.roleNode.setPosition(rolePos);
    }
