Finding Object in a List

[ktysdal]

Hello,
I am trying to figure out a simple way to search a list for a specific object, but no matter what I try I can’t seem to come up with an elegant solution.
After some time on google it seems like using List<T>.Contains Method (https://msdn.microsoft.com/en-us/library/bhkz42b3.aspx) would be the way to do it in C#, but I’m not able to figure out how to access that in flowCanvas :/

Hello,
You can use List.Contains method in FlowCanvas too.
Here is a small step-by-step for example:

1) Create a list variable:

2) Drag the variable into the editor canvas and select “Get”, to create a node that gets the variable value.

3) Drag the “Value” output of that new node into empty canvas. This will pop up a list of everything you can do with that type of value. In this case (List).

Within the List category in that popup you will see a lot of list related methods. One of them is Contains. Click it to create a new node that check if the List contains an element.

For the shake of this example, I added a few more nodes to showcase something more practical:

Let me know if that is indeed what you were after.
Thanks!

Oh wow, that was embarrassingly simple 🙂
Great! That was exactly what I was after. Thank you so much again Gavalakis.

I think the main reason why I was having a hard time getting this to work was because when you hit spacebar and search for “contains” this specific “List-Contains-Transform” node does not appear. The only thing that shows up in the search was a “Contains” node that works with strings.

PS: thank so much for adding the Duplicate and Delete multiple hotkeys in 1.3.2. They are very useful.

Hey,
You are very welcome!
I think dragging and dropping a port into empty canvas is the best way to get all nodes that are possible to be performed with that dragged port’s type 🙂
