Wanted to create a button that can add number in text box. For example. I have a text start with number 0. Once i press add button then number will increase to 1 and it goes on.

Create a blueprint widget
Add a text box
Add a button
Scroll down the details panel to “Events”
Add a “OnClicked” event
Create a public Integer variable
Drag a node of OnClicked and add a SetText(Text Box) function
Connext its target to you textbox object
Drag you Integer variable into the field
Set its value “+1” by using the “Integer + Integer” function

Thats it

Hi, you want to add 2 buttons and a Text object (set this one to “Is Variable”) to a widget. Then use the OnClicked Event of the buttons to change the Text value, something like this:

Thanks for the clear answer!
What if I want to set a certain number? Let say first click value is 1, second click is value 5, third click value is 10.

Use a branch between the last node and the operator ("+" or “-”) to check for the textbox condition. If its bigger than 1, set the true node to +5 otherwise the false to +1.

Well, depend if those will be fixed numbers you will need to add cases, like in atatch (note also i added an Integer Variable called AuxInt), but if your sucesions have some logic like 1>3>5>7>9>11 etc then you could do the maths and code more general.
