Drawbridge

I'm trying to create a drawbridge script.

Basically, I want to, on clicking the sensor, raise the drawbridge about 80 degrees ... pause ... then lower back to flat.

Usually for rotates, it's a permanent rotation so I use llTargetOmega which obviously isn't right for this.

But I can't remember how to tell something to rotate from an absolute rotation, say x to x+80, especially over a duration. I thought there was a command to do that? Or am I just having a brain fart?

I'm thinking something along the lines of Tower Bridge, just not so big or ornate

You may be thinking of llSetRot(), but the "over a duration" thing sounds like llRotLookAt() (or possibly llLookAt(), but I'm guessing that would involve a little more math in this case).

llSetRot based on current rot plus a delta value, a counter variable and a timer.

Ok probably not the neatest solution but this at least works



rotation rot_xyzq;
rotation rot_xyzq1;
integer x;

default
{
state_entry()
{
vector xyz_angles = <2,0,0>; // This is to define a 1 degee change
vector angles_in_radians = xyz_angles*DEG_TO_RAD; // Change to Radians
rot_xyzq = llEuler2Rot(angles_in_radians); // Change to a Rotation

vector xyz_angles1 = <-2,0,0>; // This is to define a 1 degee change
vector angles_in_radians1 = xyz_angles1*DEG_TO_RAD; // Change to Radians
rot_xyzq1 = llEuler2Rot(angles_in_radians1); // Change to a Rotation
}



touch_start(integer s)
{
for (x = 1; x < 35; x++)
{
llSetRot(llGetRot()*rot_xyzq); //Do the Rotation...
}

for (x = 1; x < 35; x++)
{
llSetRot(llGetRot()*rot_xyzq1); //Do the Rotation...
}
}
}

Void Singer just posted the world's simplest door script in the script library.

A drawbridge is just a door laying down.

the formula is localDegrees2Rot * currentRot requiring a cut root prim for something like ths. multiplying the .s component of the local portion by -1 will reverse the rotation.

rotation easyRot = llEuler2Rot( <how much you want to rot on which axis> * DEG_TO_RAD );

llSetRot( easyRot * llGetLocalRot() );
easyRot.s *= -1;
