Driver animation with vehicles

My apologies, for I know this must have been asked already, but I can't seem to find an applicable thread for some reason.

I have a driver animation I want to use for my bicycle. The script for the animation works fine when I "play in world/locally" and works fine when my bicycle is moving (I used Aaron Perkin's realistic vehicle script in a transparent base for the bicycle).

The problem I have is I don't know how to get the script to work automatically when the driver clicks "drive" and starts moving.

I suppose I could make the seat a poseball, shove the script in that, but that seems rather inelegant. I really would prefer that it happen automatically, without the need to click twoice for the animation and to drive it.

This is easy enough to do, you simply need to start the animation when the user sits same as you would for a pose ball. In fact You SHOULD be able to put the scripts from a pose ball into your root prim and have it all work.

Thank you for the reply! Unfortuantely, I already tried that--put it in the root prim along with the vehicle script, that is. And it didn't do anything at all. Yet it does work when I play it by right clicking on it in inventory and selecting play.

Is there perhaps a command in the vehicle script I am missing? I am using the Perkins script, modified only for handling and sit target.

hi, Virrginia,

it sounds like you want to trigger the animation with the control events that start the "motor" on your bicycle.

Experiment with copying the start animation command from the run time animation section into the CONTROL_FWD block further down in the script. Doing it this way, you'll also need to add a stop animation command in a !level & edges CONTROL_FWD block so that you stop pedaling when you let go of the up arrow (or w).

Post your code and we'll hack away at it. =D

How did you trigger it? you woudl still need a script. kage's idea is sound and I'm sure a few others will chime in once we have some code to play with

Thank you again

I should clarify that the bicycle "animation" is really just a pose that puts the hands on the handle bars. A bicycling animation would be wonderful, but I am having enough trouble as it is

So, I want the animation to run from when the "Driver" clicks "drive" (here, I rewrote it to say "ride", to when he or she clicks "stand up".

I didn't write the animation, and can't seem to open it up to look at it. But as I said, it runs when I command it to via opening it in inventory, so it seems to be working.

I'm guessing the command to start the animation needs to be in this block:
**********************************
else
{
//llTriggerSound("car_start",1);

llMessageLinked(LINK_ALL_CHILDREN , 0, "WHEEL_DRIVING", NULL_KEY);
llSleep(.4);
llSetStatus(STATUS_PHYSICS, TRUE);
llSleep(.1);
llRequestPermissions(agent, PERMISSION_TRIGGER_ANIMATION | PERMISSION_TAKE_CONTROLS);

llSetTimerEvent(0.1);
//llLoopSound("car_idle",1);
}
}
**********************************************************
And the command to stop it needs to be in this block:

************************************************
else
{
llSetTimerEvent(0);
//llStopSound();

llSetStatus(STATUS_PHYSICS, FALSE);
llSleep(.1);
llMessageLinked(LINK_ALL_CHILDREN , 0, "WHEEL_DEFAULT", NULL_KEY);
llSleep(.4);
llReleaseControls();

llResetScript();
}
*******************************************************

And for reference, here's the entire script. By the way, much of this is superfluous--I turned off the sound (I haven't got a good bicycle sound yet), I don't use a target seat prim (it didn't seem to work for me, so I just modified the sit target relative to the root prim), and I never could get the wheel animations to work either. *sigh* I am SO much the beginner here.

I've not really paid any attention to the mains cript but to get the animation to work try this

Hurrah! That worked--or at least I am getting an animation. Oddly enough though, unlike when I simply "played in world" before when the avatar was on the bicycle, now the rider is appearing a good distance about the original sit target with her legs crossed (AO is off). Hmmmm....not sure how I can fix this without being able to look at the animation proper.

I might have to talk to the animator who created the rider animation.

When you play an animation in world there is no sit target offset. The sit target offset in the script puts it 2.15m above the prim. Alter this line:

llSitTarget(<0.2,0.1,2.15>, llEuler2Rot(<0,0.2,-.1> )); 

Also I have no idea what the name of your animation is so I called it "ride".
It can be automatically obtained using the following line of code as long as it is the only animation in the object. inside state_entry add the following line

animation = llGetInventoryName(INVENTORY_ANIMATION,0);

I had already used that to position the rider on the seat (the coordinates there are the seat relative to the root prim, which is the transparent base). I tested it by having the rider click "ride", and then playing the pose animation in world.

Once I had that all set and adjusted, I added the code to start the animation automatically. That's when I got the rider suddenly floating even higher above the seat with her legs crossed (as opposed to the animation, which had the legs in a "bicycle" position). Any idea why that happened?



I actually figured that one out myself, albeit not before a few syntax errors

A customer of mine just sent me a "fix it" script the other day. When placed in the root prim along with the vehicle script and the animation script, it runs the animation perfectly. She graciously is allowing me to share it, although I'll be honest and say I can't quite figure out exactly HOW it works. (I'm still slogging my way along on the LSL learning curve). I'll post it here when I get a chance.

Here's the script. Credit goes to Reysa Sanders for this one

Edit: "Bicycle 2" is the name of the animation.

    }
}

I'd guess that it was your standard sit being triggered. The offset is from the hip joints (I think) so it was then placing you at the 'correct' distance as far as it was concerned



If you look closely at the new 'fix it' script its just the bare bones of what we had already crafted.

The changed event is triggered when you sit down and casues a request to allow animations.
This in turn triggers a run time permissions event which is starting the animation

A-ha! Still unclear on why it would work this way and not the first way, though (that is, without that sit postion glitch)

Very dumb newbie scripeter question here--what is the difference between putting the above code in a script and adding the additional script to a prim, as opposed to integrating the code into one script? Is it the same as pasting the code onto the end of a single script?

(if this is off topic, I can move the question elsewhere)

Its only dumb if you dont ask questiosn you need answering.
There is no difference, I think the difference in behaviour is just due to the sit target. For what ever reason I think the sit target originally calculated was wrong since the 'fix it' script doesnt set the sit target (which wilL give an offset of 0,0,0) and that works.

Thank you so much for all your help!
