How do I make a basicTE to load 2 objects

[Stefan13]

[ FlexSim 24.2.0 ]

I have a project with my own elevator made with cinematic and I want to make it to load 2 objects on the turntable, it looks like this

On the triggers, I got all this done

and the On Load code looks like this

on top of that I also created a MySurrogate to kinematically define the position where the box will be placed and it's called "MySurrogate1"

And I would like if you can help me to get it to load 2 objects and randomly download them on the transfer points. Varianta_2.fsm

This is just a question of giving the TE the proper task sequence. For example by pushing the items to a list and using a Process Flow to loop between loading two items and unloading them.

varianta-2_1.fsm

Though you might need to do some work to adjust the travelled offsets depending on whether the first or second item is loaded/unloaded.

And to place the object on the platen, do I need to add the On Draw trigger? Or should it be modified elsewhere?

[moehlmann_fe]

I'd use the On Draw trigger as shown in the previous post, yes. Just modify it to loop over all subnodes in a for-loop and place them according to their rank.

I tried this and it doesn't work and I get the error exception: FlexScript exception: invalid index at MODEL:/BasicTE1>variables/ondrawtrigger at line 0.

And this is the old code

[moehlmann_fe]

You loop 'i' from 0 to 1, so you need to add an offset when assigning the item variable since the subnodes start counting at 1.

Object item = current.subnodes[i+1];

[Stefan13]

It works, thanks a lot for your help, one more question, now the elevator has a single exit on the left side, in reality it has 2 exits next to each other because there are 2 segments with rollers, how could I make it have two exits so that the boxes go out on both and not translate them to the defined exit? which is now given by MySurrogate??

[moehlmann_fe]

Hm, yeah, I guess you'd need to mark the items somehow as the belonging to the first or second slot, probably by setting a label on entry. That way the second item can continue to be placed on the second section even after the first item is unloaded.

[Stefan13]

Here I'm trying to apply a kinematic and I want to move the first object to the left by translation and it doesn't work

[moehlmann_fe]

You generally need a "Create Kinematics" activity first, if you haven't already initialized a kinematics node.

[Stefan13]

I tried but the token is wearing out and it still won't move my box to the left. Sorry to bother you but this is my first time working with kinematic.Varianta_cu_conveioare.fsm

[moehlmann_fe]

You also have to specify which object the kinematic is supposed to move. And moving the box won't work, because the On Draw will readjust its position.

I don't think you need kinematics anyway. As I said, assigning a label to the items that denotes which slot they belong to and using that information in the On Draw and On Begin Offset triggers is enough to make the TE move as at least I would expect.
