Raw Value

There are occasions where we want to declaratively set a value on a property of the parent element, we can use ngt-value element to do this.

<!-- this saves us the trouble of getting access to the PointLight instance and assign 0.0001 to light.shadow.bias -->
<ngt-point-light>
    <!-- with this, we can declaratively assign a value to shadow.bias; under an ngIf or something similar -->
    <ngt-value [rawValue]="0.0001" attach="shadow.bias" />
</ngt-point-light>

Note

We can achieve the same result by using parameters property on the ngt-point-light element if we don’t have to worry about the life-cycle of the ngt-value or using control-flow with ngt-value

<ngt-point-light [parameters]="{ shadow: { bias: 0.0001 } }" />
