llMoveToTarget: removing the slowdown near the end?

I have a friend who's playing with llMoveToTarget, getting an object to move along a path, and the way it slows the object down as it starts getting close to the target is driving her nuts.

Aside from deliberately overshooting each target and using llTarget/at_target, is there any way to turn this feature off or control how it behaves? I haven't seen anything in the wikis..

Nope, that's just how it works. You can play around with things to manipulate the effect, but there's no 'damper' control sadly.

You could try decreasing the damping coefficient as you get closer to the target position. Probably something like tau=currentDistance/VELOCITY.

That's an interesting thought, I'm going to have to play with that idea this weekend

That IS the way to control it. No matter what you do, having a small range value in the llTarget() function is going to cause serious damping to occur, because, as it approaches the target, it damps more, so by setting a range of say, 0.1, you're going to get ALOT of damping. The best way is to set a range of 1.5-2.0 meters in llTarget(), and adjust the waypoint you're heading for. Typically, you dont even have to do that. I have a bot I'm working on, and you set the waypoints by setting the position of the bot, clicking a menu button, and repeating. When the bot is patrolling the waypoints that you have setup, I use a range of 1.5 meters, it doesnt really make much difference that it's actually triggering at 1.5 meters from the target. I've found 1.5 meters is a good range value for llTarget, as the bot doesnt slow down so much, and his motion appears relatively fluid. I imagine decreasing the damping as it approaches the would work, but that's alot of extra code and execution overhead for something that is easily fixed by changing one variable.. range, from whatever (low I'm sure) value you have set, to 1.5. Give it a try first, and see if you can fix your issue that way before you dive into timer events and recalculating tau over time.

if you want to see my bot in action, he's in testing about my store, feel free to check it out, and if I'm around feel free to approach me with any questions.

Thanks for the replies.

I was just gonna add a JIRA suggestion to change this, followed up possibly by some harrassing of Sidewinder, and found there's already one there.

Please give http://jira.secondlife.com/browse/SVC-1479 a look & a vote if you'd like an easier way to control this stuff.

voted for it, Meade.
