Sir you failed...
You put setVolume() , which will just lower the volume, not STOP the sound.
So basically what you did is to lower the sound, and the sound will keep looping anyways.
stopAllSounds should do the trick i think. It'll stop all sounds (only on that frame though)
And Later i will add a game explaining you how to make Simple(And later advanced) Sprite animations which will include where to get them , how to make a good use of them, and some framework which is the hardest part, and tween motion as well.
Advanced will include transitions etc. Scenes, and others, as well as how to put sounds so every time that the soldiers shoot, the sound will be triggered.
I'm sorry for taking so long to update. I been having some problems, so i couldn't update. The next update will be another MGS game like this one, but not this one updated. So i'll be making Metal Slug Scene Creator 2 which will include:
Many more soldiers(and type of soldiers as: Marines, Black Operations soldiers, Regular Soldiers, and some of the Heroes, and if you want, some other sprites from other games as Zero from Megaman.)
Vehicles: As Tanks, big planes, helicopters and others(ships probably.)
Sounds: Everything will have sounds.
Others as: No shaky animations, perfect. I will try to improve the definition.
I will not make unlimited amount of soldiers because it will lag too much the game, but i will add a decent amount of soldiers.
if talk so much, try making a game like that one, then we can talk, you all are a piece of stupid azzes, and you don't even know about scripting and gaming, so you can't fu**** say something about this game. YEA when you make a game better than this one (if you can you bunch of retards) then we can talk. Wrong names? I dont think so... i've heard so many times the predator being called "The Hunter" ... look in the freaking movies. Who cares, make a game like this one, and we'll talk.
