How do I count an instance variable?

Hello

The npc sprite have an instance variable which called "task" and it is a text variable. This variable can be movetower or woodcutting or idle and so on...

So I need to set a global variable which include the total amount of idle npc. I have to count only the idle values.

I tried to use the pick by comparison and a few more fuction but these are not working. Can you write me an easy solution please?

Thanks in advance!

Use the pickedcount expression.

https://www.scirra.com/manual/133/common-expressions

npc sprite variable = "idle", set global value to npc sprite.pickedcount

I tried this but it is still not working. I dont know what is the problem...

Are you using .pickedcount and not .count?

.count will count all instances where as .pickedcount will only count the picked instances, as the names suggests.

Oo my god.. i got it! the proplem was that i wrote with upper case letter the i in the instance variable but i use lower case at the conditions... no comment

So i use this now:

Pick by comparison. ---- set global var - npc.pickedcount

Working properly now that i know its case sensitive.

Thanks
