For the past week I have been looking for appropriate sounds to add to the rifle. I have been looking through websites such as Soundsnap and Gamebanana Day Of Defeat: Source for sounds to use for shooting, reloading and aiming.

I also had to record the sound files for the aiming and lowering the gun (currently called ‘Holster’ but this will be changed). I used the game Garrysmod to download some weapon packs to record the aiming and lowering gun sounds to edit on Audacity.


Matching sound to the animation

I then had to match the sound to the animations. I had to crop the sounds using Audacity to help fit with the animations, however I also had to make sure the sounds didn’t suddenly end, especially the shot sound effect. I solved this by making sure the sounds faded out gradually to prevent a sudden lack of sound once the sound file finishes.

The biggest problem I faced was matching the sound for the reload sequence. I first wanted to try adding Animation Events for each reload segment however I felt by just creating variables for each sound clip and playing them once in code works just as well.


Animation problem between shooting and reloading

I also ran into a problem where shooting and trying to reload would cause the animation for reloading to wait until the shooting animation finishes. Without sound this wasn’t a big problem, however with sound the sound ended up being out of sync with the animation. I attempted to lock it so players cannot reload until the animation finishes by using animator state info. However I was facing problems of either the animation for reloading not working or the trigger wouldn’t activate.

As a temporary solution I’ve allowed the animation for shooting to run into reloading if the player presses the reload key (as shown below).

What next?

The rifle is almost complete. I want to add a particle effect to when the player shoots the rifle and I also need to fix a bug with the gun being able to shoot while reloading if the gun is loaded. I also want to look into adding recoil to the rifle which moves the camera slightly.
