How do I make ammunition and change it

Hi all! I came across an idea in Construct 2. I was wondering how I can make ammunition to my player and change it when he fires.

Please be more specific... there are many ways to do what you are asking and many different possible expectations.

Like when I maybe declare a variable and check the condition of it everytime I fire. And when it reaches 0, it reloads itself.

Here is a thread of a similar nature, close to the bottom is a link in my post to a .capx I put together for him. It does more than what you ask... maybe it will help you get your head around how to do what your after.

Otherwise, it's pretty simple. Just make a variable called ammo. Every time you fire subtract 1 from ammo. When ammo = 0 set its value back to start amount and play reload animation/sound/ or message.

Maybe also add an action: wait X seconds, so there is reloading time?

Okay, thank you all for the replies!

If you want to display text of how much ammo is available do this

Ad global variable "Ammo"

Everytick set text to "Ammo:"&ammo

Rightmousebuttonclicked

System

Subtract 1 from ammo

Ammo is less than < 1 add 10 to ammo

That's how I do it maby someone knows easier way I'm I started programming 3 months ago

I update my text boxes when I change their value. It's just one extra line of code per and less updating.

You could also update something like this every x seconds using .01 or .5 and never notice visually but would cut down the number of updates a min drastically.
