Hi all,

I’m calling a Draw/SheatSword() function with a event function via Mecanim.
It works, but I have the problem that the rotation is wrong when the sword is sheated. The localRotation vaules are not the same I coded.

Besides this everytime the Draw/SheatSword() function is called I am getting this error message:

UnassignedReferenceException: The variable weapon of ‘NewPlayerControl’ has not been assigned.
You probably need to assign the weapon variable of the NewPlayerControl script in the inspector.
NewPlayerControl.DrawSword () (at Assets/Scripts/Entity/Player/NewPlayerControl.js:410)

I assume the rotation can’t be assigned because he has no weapon variable when the function is called an generates an error.

This is my code, I can’t find an error.

var weapon : Transform;
var myHandBone : Transform;
var myHipBone : Transform;

function DrawSword() {
	weapon.parent = myHandBone;
	
	weapon.localPosition.x = -0.1647566;
	weapon.localPosition.y = 0.05176726;
	weapon.localPosition.z = 0.001803763;
	
	weapon.localRotation.x = 7.513212e-05;
	weapon.localRotation.y = 249.9859;
	weapon.localRotation.z = 270.0002;
}

function SheatSword() {
	weapon.parent = myHipBone;
	
	weapon.localPosition.x = -0.05071573;
	weapon.localPosition.y = -0.2928329;
	weapon.localPosition.z = 0.112793;
	
	weapon.localRotation.x = 34.14093;
	weapon.localRotation.y = 241.5118;
	weapon.localRotation.z = 259.439;
}

I hope someone could help me.

Best regards,

According to the error message, the problem does not come from the script but from your scene. If you click on the GameObject which this script is attached to, the “weapon” field is probably saying “None”, which means you have to assign your weapon in the editor (drag and drop). If the weapon is instantiated at runtime, you will need to assign it in the script.
