Scripted rotation doesn't stay in sync with hand animations and isn't as smooth to look at.
in my case this is not critical. a simple rotation of objects on the similarity of planets is ok. (it's more like telekinesis, hehehe)

Hi! Question about simulation of juggling. How to make two - three objects to rotate in a circle and whether it is possible at the same time to wear them? Please, help!
Thanks in advance!

Just file a trouble ticket.
I believe this is the better way.

SetEnginePosition() { vector diff; if (fFwd >= 0.0) // moving forward, don't tip on your nose { diff = llGetCenterOfMass() - llGetPos() + <-3.25,0.0,0.0>; } else // Moving backwards, don't tip onto your tail { diff = llGetCenterOfMass() - llGetPos() + <0.0,0.0,0.0>; } llSetVehicleVectorParam( VEHICLE_LINEAR_MOTOR_OFFSET, diff ); }Wow! Thank you very much for this! I will try it! So it's a script, not construction?

Hello, I build a small seaplane, but when on the water (it floats ok) wings or nose go under the water. On the land all ok. The root is a 0,5 prim cube. Is it script or construction (primmy)? Please help! Thank you!
Seaplane is about 3x3 meters

Hello! I'm trying for the first time to build a seaplane and here I got such a script. The script is excellent, the plane flies, but I can not add the ailerons, rudder, flaps. in the script I see these words are encountered. Please help add them. Thanks for any help.

Here's what I got. Now I can control the brightness of the glow by entering values from 0 to 10 in the chat . But if you enter a value more then an error occurs. Which is understandable, it is not possible to glow brighter.
Is it possible to combine these two properties with a "light" toggle command and brightness 1-10 control?

iSwitch is binary information, true or false (wich is an integer to LSL)
light intensity is multiplied by the iSwitch state, which is 1 for TRUE and 0 for FALSE, the * is simple math it ... multiplies numbers =^.^=
3 minutes ago, Rolig Loon said:LSL does not have true Boolean variables. Instead we can use any integer variable and assign it a value == 0 or != 0. That is, any integer variable can be a simple TRUE/FALSE, or ON/OFF binary switch. So if iSwitch == 0 .......
I think I understand. If multiplies by one then the light is on, if zero is not.

See if you can figure out why this does the same thing ....
listen (integer channel, string name, key id, string message) { iSwitch = !iSwitch; llSetPrimitiveParams([PRIM_POINT_LIGHT,iSwitch,<1.0, 1.0, 1.0>,1.0,15,0.750, PRIM_GLOW, ALL_SIDES, 0.4 * iSwitch]); }
It works! But I can not see yet what's the matter there ... it seems like it's related to the symbol *

I even conducted such a wild experiment and made a model without floor and ceiling, subsequently replacing them with mesh cubes. and all to no avail. I come to the conclusion that the matter is in the physics of the game and we all walk a little in the air ...

Hello! I have this situation with the physics of the mesh.
I upload the building, do the analysis, set it to prim - all successfully. But when I try to walk on it, I stand a little in the air.When I rez a prim, it appears where it should be. But if you turn it into a physical it pops up a bit. And it does not even touch a physics highlighted blue and hangs over it. Why is this happening?(You can see a small doorstep, I did for it a separate cube in the physics, I tried even the model completely without the doorstep but the situation repeated.)
Please help!
THANK YOU!

If you don't hit the analyze button, the physics mesh will be a so called Triangle-based physics mesh. Tri-based physics will secretly switch to convex hull physics by the physics engine, when the object is set physical. Now when standing up, the server seems to be quite slow in setting it back to prim physics. Hence, if that sroom is one physics shape, the Avatar will be pushed out. To avoid the secret physics type change, the physics mesh needs to be decomposed (Analyze) in the uploader.
Hello! Thank you very much for the answer! I do not know why, but the physics worked for me without analysis... but this happened only once! Later I tried to change something but I did not succeed. So you really helped !!! Much grateful!
By the way do you really need to apply analysis to all the elements of vehicle?

I have 2 questions.
Will the boat be set physical when sitting on it?
How did you upload the physics shapes? Tri-based, or decomposed (Analyzed)?Physics I do separately and at loading I choose "from a file". and at the end switch the "Convex Hull" to "Prim".
Boat will be physical and your friends even can walk on it!
Do not hit the analyse! I used simple physics made from individual cubes (per cube on each side), keeped only the doorways.

I made a simple cubic physics and the problem solved now. Thanks for taking a part!

Did you use hollow prims to build the boat? It could also be part of the script you are using, intended to give the user a push out of the vehicle upon exit (who likes to stand in the middle of their car ayways?)
Yes I use a simplified model without windows with a void inside. Maybe you could tell where in the script to look for a moment of ejection overboard?

I bet it is some unlucky combination of physics and boat shape. When you get up are you by chance inside a physical prim? That could explain the effect.
Thanks for answer! I checked, in the place where I throw out, I can walk freely. can the transport when I get up become a hull? or the wall is too thin ... what if in this place to attach a thicker unseen prim?

It means what it says. You can't have a physics-enabled object with a physics cost of more than 32.
Hello, thank you so much for this post! It helped me a lot! I was just looking the way to reduce physics cost.

Hello! I build a houseboat and I have such a question. When I get up from it, it pushes me overboard through the wall. How can this be avoided? please advise!
Boat is mesh and walkable inside.
Thanks

Hello! tell me please how should the script of the lighting device look like, which is switched on/off by command in the chat, and illuminates the ambience, but with only one surface glowing?
Danke, Muchos gracias, Thanks!
Congratulations.

Uneven particle emission
in LSL Scripting

Hello! I have a question. My seaplane during the movement on water produces foam trace. But the emission goes by impulses, uneven. Help please make the trace smoother and more continuous! Thanks in advance!
