PlayWeaponAnimation Does Not Play My Weapon Animation

[mahdavi]

Hi everyone,
I have a Pawn class that extends from UTPawn.
My game in Third Person Mode.
I have a new weapon and I want to play new animation when weapon fires,
For using this weapon my Pawn should play animation too, and it works correctly.
But my weapon animation does not play.

my weapon class extends from UTWeap_RocketLauncher

class WPSling extends UTWeap_RocketLauncher placeable ;
...

simulated function StartFire(byte FireModeNum)
{
	if ( bWaitForCombo && (UTBot(Instigator.Controller) != None) )
	{
		if ( (ComboTarget == None) || ComboTarget.bDeleteMe )
			bWaitForCombo = false;
		else
			return;
	}
	//PlayAnim('WeaponFire');	
	PlayWeaponAnimation('WeaponFire',2.0,false);
	Super.StartFire(FireModeNum);
}
...

DefaultProperties
{
	bMeleeWeapon=true
	// Weapon SkeletalMesh
	Begin Object class=AnimNodeSequence Name=MeshSequenceA
		bCauseActorAnimEnd=true
	End Object

	// Weapon SkeletalMesh
	Begin Object Name=FirstPersonMesh
		SkeletalMesh=SkeletalMesh'Slingshot.Slingshot'
		AnimSets(0)=AnimSet'Slingshot.Slingshot_Anim-02'
		AnimTreeTemplate=AnimTree'Slingshot.SlingShot_AnimTree'
		Animations=MeshSequenceA		
		Rotation=(Yaw=-16384) //????????????????????????????????????????????????????????
		FOV=60.0

	End Object
	SkelMesh=FirstPersonMesh
	AttachmentClass=class'TBGame.TBGame_WPSling_Attachment'

	Begin Object Name=PickupMesh
		SkeletalMesh=SkeletalMesh'Slingshot.Slingshot'
	End Object
	
	InstantHitMomentum(0)=+60000.0

	// define Fire Type 
	WeaponFireTypes(0)=EWFT_Projectile
	WeaponFireTypes(1)=EWFT_Projectile
	FireCameraAnim(1)=CameraAnim'Camera_FX.ShockRifle.C_WP_ShockRifle_Alt_Fire_Shake'

	WeaponFireAnim(1)=WeaponFire //????????????????????????????
	WeaponFireAnim(0)=WeaponFire
...

I changed my weapon class, it extends UDKWeapon , my weapon animation play correctly but new problems appear.
after pickup new weapon the current weapon still in player's hand. because it attached to hand.
in the other world when it extends from UDKWeapon the switching weapon does not work correctly.
Please Help me.

Have you made a new class to extend off UTAttachment_RocketLauncher ? this is where the 3rd person animations are set

[mahdavi]

Yes, I wrote attachment class
I should play animation in attachment class ?

[HKLM]

For example:

class UTAttachment_RocketLauncher extends UTWeaponAttachment;
/** list of anims to play for loading the RL */
var array<name> LoadUpAnimList;
simulated function FireModeUpdated(byte FiringMode, bool bViaReplication)
{
 if (FiringMode == 1 && Instigator.FlashCount == 0)
 {
  UTAnimNodeSequence(Mesh.Animations).PlayAnimationSet(LoadUpAnimList, 0.5, false);
 }
 else
 {
  Mesh.StopAnim();
 }
}
simulated function ThirdPersonFireEffects(vector HitLocation)
{
 Super.ThirdPersonFireEffects(HitLocation);
 Mesh.StopAnim();
}
/** 
*   Optimized equivalent of calling ThirdPersonFireEffects while in splitscreen
*/
simulated function SplitScreenEffects(vector HitLocation)
{
 Super.SplitScreenEffects(HitLocation);
 //Mesh.StopAnim();
}
simulated function FirstPersonFireEffects(Weapon PawnWeapon, vector HitLocation)
{
 Super.FirstPersonFireEffects(PawnWeapon, HitLocation);
 Mesh.StopAnim();
}
