How to get the speed of an item at the end of a basic conveyor?..

Hi,

I'm playing around with the basic conveyor, and set it so that i have a variable starting speed, variable final speed and variable acceleration, how can i capture the speed of the item at the end of the conveyor?...

Call bcgetitemkinematics() to get the item's main kinematic. Then call getkinematics() for KINEMATIC_VX.

I tried that but i guess i'm making some mistake when using the commands. What i did is:

treenode nodo_kin= bcgetitemkinematics(current,item,0);

pf(getkinematics(nodo_kin,KINEMATIC_VX));

setlabelnum(item,"vel_final",getkinematics(nodo_kin,KINEMATIC_VX));

I keep getting 0.0000 at the console and the label...

Yeah, in flexscript, at least for now, you need to pass parameter 3 and 4 explicitly, so this should work:

getkinematics(nodo_kin,KINEMATIC_VX, 0, time());

We'll fix this for version 5.

Still getting 0.0000, the code using now is:

treenode nodo_kin = bcgetitemkinematics(current,item,0);
pf(getkinematics(nodo_kin,KINEMATIC_VX),0,time());
setlabelnum(item,"vel_final",getkinematics(nodo_kin,KINEMATIC_VX),0,time());

Attaching the model, i'm using the code on the decision point OnClear

i also tried bcgetitemkinematics(current,item,1); just in case, it's supposed to be 0 for the main conveying kinematic right?...

You actually passed the parameters: ,0,time() as parameters to the pf() and setlabelnum() commands, instead of into the getkinematics() command.

Also, make sure you're calling bcgetitemkinematics(current,item,0); not bcgetitemkinematics(current,item,1); That's what the model you sent me has in it.

Can't wait for version 5 (version 5 would yell at you for this error)!!!

doh!... that happened because i was just leaving office, and tried it in a hurry, gonna check it againg tomorrow, thanks for your help!...
