Looping through data table rows.

[volk.SWAG.en]

So i have a blueprint that gets x- and y- coordinates out of a data table and then moves objects to the locations. After that it stops. How do i make a loop that repeats the same process for the next row and so on?

Any way to foreach loop rows in a data table?

I believe you are looking for something like this. First you can get data table row names and do a for each loop on that, this feeds into the get data table row node and finally add the results to an array that you could easily work with. Example of what you could do on begin play. You could also instead of adding it to an array at the end (which you need to plug the array you make into): break the out row struct and do calculation on the data first before adding it to the array or not adding …

The loop isnt working. Did i make a mistake?

[Extrone (Arjun Subhash)]

Looks correct. What do you mean by not working?

My objects are not moving anymore. If i set the row name manually their moving to that 1 location. But with the loop nothing is moving.

you can do something like that, such that it only go to the next row index when the object has reached the current location coordinates:

I moved the objects with “Set Actor Relative location”. It doesnt work with “move to location or actor” note

Is it not possible to loop the Set actor relative location?

[Arodi007 (Pixiebell Games 💼)]

when using the Move To, it required the setup of a nav mesh.

if you doing a Set Actor Location directly inside the loop body, the for each loop will do everything at one go, so you will see only the last index location.

When i try it with a “For each loop” and connect a print note to “completed” it instantly prints. It seems like there is a problem with the array bc. the loop instantly finishes before it even executes.

[Arodi007 (Pixiebell Games 💼)]

yes that how for each work, it will do everything at one go.

so you will need to do a manual loop with an event that will tell (on destination reached)

you can also use a timeline with a lerp to move your object and when it completed, call the next location.

Im already moving the objects with a timeline and lerp. how do I call the next location?

Assuming this is still the same thing.

just like everynone just posted but with a custom event at the begining and a call that custom event after the ++
