Well, I saw and played with your vehicles (had to tweak the Unreal 2 vehicles textures to not crash my UT, LOL), and I must say that the physics are extremely well done relative to that the engine has to offer.
But, still i have a few sugestions and bugs if you are interested to include them in a next release:
Sugestions:- Boat physics (I think is not to hard to make, just one point underwater while the code sees if the actual boat stays out of the water);
- Jets turn rotated: when you turn a jet, it stays with the same roll, it would be cooler if your could make them roll, like 30 to 45 degrees each side;
- Showing the actual speed using the rocket launcher/flakcannon ammo count font, in miles or kilometers;
- Make the submarine emerging with space and imerging with crouch too;
- Hovers with crouch: sudden movement down, Ut2004 manta like;
- Add the possibility of make a turret or another vehicle weapon animated when firing, like adding the fields, as struct variable or not:
Quote:bool Animated; //if the turret is animated when firing or not
name FireAnim; //fire animation
name AltFireAnim; //alt fire animation
float FireAnimRate; //fire animation rate
float AltFireAnimRate; //alt fire animation rate
float FireBackTime; //fire tween time in animation
float AltFireBackTime; //alt fire tween time in animation
name StandByAnim; //Anim when the turret isn't being fired (stopped animation, so it should be 1 frame long)
//When firing:
LoopAnim( FireAnim, FireAnimRate, FireBackTime);
//When alt firing:
LoopAnim( AltFireAnim, AltFireAnimRate, AltFireBackTime);
//When stopped:
LoopAnim( StandByAnim, 1.0, 0.0);
//All this would occur only if Animated=True of course
Bugs:- The hovers should detect water and move above it, like manta in UT2004 for example, but it is falling in the water;
- Some turrets rotate themselves to the max of one side when your reach the max of the opposite side, after fire.
If you add and correct these, I think that your vehicle mod would pass from EXCELLENT to HOLY SHIT!!
Hope you like the sugestions.
EDIT: I will subclass a few of your vehicles to make those fixes (already fixed the Hove 1st bug, added Boat Phys and added the animated turrets support by myself), unless you tell us if you are going or not make a next release with these fixes/features.
Remember that you have the best vehicle mod for Unreal/UT in hands

(So great mod, but it seems to be lost in users memory, is there actually any server with these vehicles?)
