How do I script, or use available scripts to make an object not move until a certain time frame?
I have some objects that I cannot get to stop wobbling, and want to keep them still until just before they are struck. |

Hello Kena, You can use this RsObj.
Change the value of "From" and "Until" to the range of keyframe time you want your script obj running. ;)
As example from below image, your script obj will running only from keyframe time 100 until keyframe 200.
HTH! |

Thanks Johny! I really appreciate that.
have a bananna! :banana:
EDIT: oh, darn... I should have been more specific.... That did not do what I wanted it to do.
What I need is to activate the physics of the object at a certain timer event.
12167
I want to activate the physics of my object when the current time reaches, say, 17.2
So what I need is something that will put that check in at "Active" at that point.
But you can keep the bananna :D |

I don't really know this stuff myself but I thought you could create a physics "reaction" by running your simulation then convert the result into a clip and then slide it anywhere you like on the time line. Then you need a clip of the static object for the first part of the anim.
(Of course this is from someone who has read some chapters of the manual but never actually done it so I could be talking through my hat.) |

Go inside the object in question and export the PhysObject/Constraint/Active attribute. With your object selected add this attribute to the Keying panel. Then you can record a keyframe with it off until needed.

Nice one Johny! :) |

Actually, instead of keyframe, I was trying to do a completely physics related animation. so I start the physics recording, and a ball rolls down and hits the object, but the object just sits there and wobbles until the ball hits it to knock it down. It doesn't look too real that way. making the cube fatter causes it to not fall over, but get pushed instead. Or it causes it to fall down immediately.
here is a quick test. Note that the ball doesn't even come into the screen before the block is down.

Sorry Kena, I search and could not find a way to activate physics of an object while physics is running in TS7.51.
Maybe there is an other way you can choose to do your animation. |

Dont worry Kena, here a prototipe RsScn file for show how to make some phys obj run later on your setting time. :)
No more banana please. This time I want a pineapple. :D |

Thanks Johny... I will try that out when I get back from work tonight. See what it helps with and all. I would have picked it up yesterday, but I was not even online. worked all weekend pulling an extra 20 hours in 2 days. so I had to catch up on sleep. |

well... It looks like what I'm trying to do, so all I have to do now is try to incorporate it into my scene and see if I can get it to work.
Thanks again Johny! |

You're welcome Kena. :)
Wish to see your phys animation on Caligari monthly animation contest. :D |

I was hoping to have it done for this month.. maybe next month... Having a problem though. I have more than one object to delay, and they have to delay in a series about .500 time-clock after each other. When I tried to duplicate your wonderful script, the first one fires, but the rest do not.
Here is your example with an added object to it.
When you put a check on the timer events, the second one seems to make everything else loop.
remove the second timer event and connect the first to the second script instead... and since the check goes away with the first one, it does not fire the second one.
Maybe you could take a look at it and see what is going on? |

For easy explaination let rename:
Timer Event become TimerEventStep1
Timer Event, 1 become TimerEventStep2
MainScript become ScriptStep1
MaintScript, 1 become ScriptStep2
Kena, you make two 2 error on you post RsScn file:
1. You not change script code on "ScriptStep2" obj on line 10
you must change it become TimerEvent = Space.CurrentScene()+"/TimerEventStep2";
where TimerEventStep2 is timer event name that call the ScriptStep2
2. You connected physEngine continue flag with 2 links (one from ScriptStep1 and one other from ScriptStep2)
This is can cause make PhysEngine continue port receive value 1 and value 0 at the same time!!!
To make it work safer, you only need connected one input to it. On this case, you must connected the lastest ScriptSteps obj (ScriptStep2 on this case). REMMEMBER!! only connect last step PhyContinueValue's port to physEngine continue port.
here the work RsScn.
Hey where my pineapple. :D
PS: remember the steps: AllTimerEvent active flag or reset all positions, then start physEngine. |

ya got one anyway! Now... If I add a script 3 would I plug the continue into both script2 and script3?
I will do some experiments and see what I get
EDIT: OK - add a third, and make sure that the continuevalue is moved from the second one to the third one, and change the script to match the third timer event. Got it! |

Steep learning curve... How do I script the reset so that it puts objects not only back at x y z (which I figured out) but also the rotation?
I run the script the first time, and the rotated cone snaps back to it's original rotation, but when I run the script the second time after resetting position, it does not.
Since I have several blocks that tip over , I need to be able to reset them to their original positions and rotations.
Here is the script so far:
function Execute(params)
{
coneA = Space.CurrentScene()+"/ConeA";
coneB = Space.CurrentScene()+"/ConeB";
coneC = Space.CurrentScene()+"/ConeC";
coneD = Space.CurrentScene()+"/ConeD";
Space.NodeMatrixElement(coneA,'tz')=8;
Space.NodeMatrixElement(coneA,'ty')=0.596;
Space.NodeMatrixElement(coneA,'tx')=-2.727;
Space.NodeMatrixElement(coneB,'tz')=8;
Space.NodeMatrixElement(coneB,'ty')=2.051;
Space.NodeMatrixElement(coneB,'tx')=2.213;
Space.NodeMatrixElement(coneC,'tz')=8;
Space.NodeMatrixElement(coneC,'ty')=10.804;
Space.NodeMatrixElement(coneC,'tx')=-2.367;
Space.NodeMatrixElement(coneD,'tz')=8;
Space.NodeMatrixElement(coneD,'ty')=5.887;
Space.NodeMatrixElement(coneD,'tx')=-3.910;
} |

You would add roll, pitch, and yaw.
Space.NodeMatrixElement(coneB,'roll')=0;
Space.NodeMatrixElement(coneB,'pitch')=0;
Space.NodeMatrixElement(coneB,'yaw')=0;
Here is a jScript macro I recorded to make it easier to Start and Stop the simulation. The jScript Macro Recorder is your friend. :) |

Hello Kena, here I add jscript obj for save or restore your objs matrix. I dont use array for simple and easy for understand and modification by you. but you must see inside ConeA, B, and C, I added Owner name obj (get from System=kernel library). Please examine the link new link from coneA,B and C to SaveorRestore obj for learning. You can manualy add matrix4,5,... and objName4,5,...n if you have more objs.
Kena if you have many objs, please check trueBlue suggestion RsObj Maybe its help with one button click for start you phys animation rather than manualy active timerEvent one by one before run tS phys. ;)
Good Luck! :) |

Thank you both! I tried the jscript macro recorder, but it didn't seem to want to work right. but at least it worked for you guys!
I will try these out when I get back from work tonight. :D
P.S. I LOVE these forums! So nice to have such a helpful community. |
