Trying to make a sub

ok I'm trying to make a submarine, now I know that using a mod boat script won't work because it hovers over the water, never under. what I understand I'll need to use a balloon type vehicle script but I need to know how to make it so I can't go past the water hight *llWater()*

now if anyone has a submarine script that they can give me a copy, or tell me where I can find one that would help alot

You could probably use your boat script, but then make sure to set the
VEHICLE_FLAG_HOVER_GLOBAL_HEIGHT
And remove the
VEHICLE_FLAG_HOVER_WATER_ONLY

From what I've seen here:

thank you, but the issues still remains about not being able to be move above the water line

I thought there used to be a submarine example in the wikki library?

I haven't found one yet, if you can find a link with it, that would come in handy

I made a couple subs that use VEHICLE_FLAG_HOVER_GLOBAL_HEIGHT. To keep it from floating above the water I used a timer checking it's position. if it raised above the water level the sub would be pushed back down

Use llWater to get the water level and llGetPos to get the position

then just check that pos.z doesnt go above llWater.

I used soemthing like

vector pos = llGetPos();
float surface = llWater(ZERO_VECTOR);

if (pos.z >= surface)
{ how you want it to behave }

if you put this into the control part of a vehicle script you can get the sub to check it's height each time a control is pressed.

Also think about changing the linear motor power or bouyancy in the if statement.

I had the linear motor ramping down the nearer you get to surface and actually producing negative power if you are at the surface

think about

if (pos.z + 1 >= surface)

etc to get the effect your after.

I actually put the code into the part where the up control was checked but it could go in the main control section to take effect whenever a control is pressed.

I am at work right now so I can't post the code as I used it but that's the basic premise. Just play around
