Hitech already bases the explosion sound delay off the speed of sound. How do you convince him to ignore the physics of sound he introduced with the new sound system? Unless you ask him straight faced to chuck it for what you want, I'm asking my questions based on what he has already created as the standard. Chewing on me for asking these questions does not accomplish anything with Hitech to get him to stop using the physics he has programed into his game. It's not my fault he decided to make this aspect of the game realistic.
It looks like you have a much larger wish to present him with anyway.
Remove GV icons so planes with bombs cannot see them.
Set the collusion bubble around all speedtree vegetation objects to no collision so you can spawn and drive with no hindrance to your objective.
Destroy GV's hurtling down mountain and cliff faces if they achieve more than the real maximum speed of that vehicle.<---- I agree with this.
Ignore the physics of the speed of sound and instead add stereo directional sound effects to the passing through atmosphere of steel objects traveling faster than the speed of sound. Even if the steel object is traveling pointing straight at your position to help you locate hidden tanks. The anime series spin off from Sword Art Online, Gun Gale Online has a line of aim lazer that flashes the bullet trajectory just before the gun fires which would work pretty good in AH3 tank combat since you want some kind of a directional indicator.
You are aware by introducing the speed of sound physics to cannon fire, you don't hear the one destroying your tank anyway, while with an air ripping sound for the round, you are still dead. With a miss, the delayed boom or air ripping sound, even if it has a directional component is not saving you from a competent tanker in this game. I run into that problem a lot flying a storch and listening to the cussing on the ground. Because my guys were waiting to hear the shutdown hidden enemy tank's shot boom to locate him. Half the time I can drop a flare right on the enemy tank and they still get killed if he's shut down. Mano and his friends shut down in tree clumps and can't be seen driving my guys nutz all the time by cherry picking them. Mano and company seem to have quite the mad skills in tanks and appear not to be impeded by the sound system, speedtree objects or, having icons attached to their tanks. Some of my squad mates have adapted to AH3 at that skill level and are impressive tankers.
