How to make a character hold a weapon?

[suicaokhoailang]

I have two seperate models in Blender: a guy and a sword. I don't need anything too complicated, just something like attaching the sword to the guy's hand. I tried creating a bone for the sword, made it the hand bone's child so it could animate alongside with the hand, then joined the two meshes together. Now I can export the model just fine, but when I try adding a simple animation, the exporter throws some weird errors. I think I did something wrong, what is the right way to do this task?

Nevermind I figured it out. 

WARNING: The following armature not visible in scene thus ignored: Armature

I hide the Armature to view the animation more clearly, and it f*cked up the exporting process.

Yes: 

sword.attachToBone(skeleton.bones[34], character);

I made a small bone search function by name, which can help.

var searchBoneByName = function(skeleton, searchBoneName) {
    var index = ;
    for (var i = ; i < skeleton.bones.length; i++)
    {
    	if (searchBoneName = skeleton.bones.name) {
    		index =  i;		
    		break;
    	}		
    }
    return index;
};


sword.attachToBone(skeleton.bones[searchBoneByName(skeleton, "main_gauche")], character);

I add the function "getBoneIndexByName" in the engine (v2.4) to do so:

var indexBone = skeleton.getBoneIndexByName("hand_left");
sword.attachToBone(skeleton.bones[indexBone], character);

There is a fixed bug in skeleton animation for Blender.  Since you are doing that, you should definitely move to version 4.4.4

Thank everyone :D, I swear this stuff's been driving me nuts for hours.
