Scaling an object along the y-axis using Haxe

ArmoredDP · March 8, 2021, 8:18am

Hie there, I would like to know how can I scale an object along the Y-axis using Haxe code. I tried object.transform.scale( axis, float value) just as we do in rotating but I failed to scale. Please show me the single line of code I can add using Haxe Code.

Hi, @ArmoredDP

You might need to call object.transform.buildMatrix(); after scaling. Please try that.

	function composeDelta() {
		// Delta transform
		dloc.addvecs(loc, dloc);
		dscale.addvecs(dscale, scale);
		drot.fromEuler(_deulerX, _deulerY, _deulerZ);
		drot.multquats(rot, drot);
		local.compose(dloc, drot, dscale);
	}

	/**
	  Update the transform matrix based on `loc`, `rot`, and `scale`. If any
	  change is made to `loc`, `rot`, or `scale` `buildMatrix()` must be
	  called to update the objects transform.
	**/
	public function buildMatrix() {
		dloc == null ? local.compose(loc, rot, scale) : composeDelta();

		if (boneParent != null) local.multmats(boneParent, local);

		if (object.parent != null && !localOnly) {

Best,

Unbelievable, I was forgetting to call buildMatrix() after scaling. Thanks @QuantumCoderQC. Thank you very much, its now scaling properly.
