To change the score value, I've added a custom event and called it setScore . This custom
event will be working on setting the value of the Score variable by adding 1 to it using the
integer + integer node. The final result of the score value will be displayed in the UI using
the Set text node. Keep in mind that you can use whatever values you want, as long as you
are using the add node. This node will be working on adding the first passed integer value
to the second passed integer.
I wanted to follow a new method to change the value of ammo, which is closer to the code
environment that I have used over the years. It is called passing parameters. Basically,
when I called an event or function, I wanted to send the exact new value directly to it, and
then use it to set the ammo text based on the passed parameter. To add this type of paramet-
er passing, I've added a new custom event, called it setAmmo , and after selecting the node
in the side panel, I've added a new input to Inputs , set its type to Integer , and set its name
to ammoAmount . Now any call to this event will require passing an integer value, other-
wise it will use the default which, is set to 0 for now.
Finally, I used the passed ammo value from the AmmoAmount parameter and set it as a
string to the Set text node, to change the proper UI text.
