Bear with me, I don't use construct as often as I would like....
Try:
object1 on collision object2 ----------- destroy object1
--------- globalvariable1="a"|globalvariable1="b"|globalvariable1="c"=1 ------- subtract 3 from globalvariable2
Is there a way to do a | in the midst of comparing global variables? I just see a drop down that I can't edit other than choosing one. If my understanding is not lacking, I would have to do each global variable= "whateverletter" as a separate sub event and that is what I was attempting to avoid. Eventually there will be 18 different possible values for globalvariable1 in this case (that mix and match combinations of 1 and 5), and 8 subevents already, each with another condition attached that is similar to the prior compare global variable, if I get it the way that I want. And this process will then need to be done an additional 18 times.
A regexvariant would be
test regex
string: globalvariable1
regex: "^[abc]$"
flags: ""
If you need to check for variable contents (a not being a string, but variable name), then the variant without regex will be easier.
I didn't know that test regex was a thing, this may work, though it was not what I originally was hoping for. I'll have to do some more research, but I mostly would still Just like to know the proper format for finding comparing a global variable to multiple possibilities in text form
if I'm not being clear, when I'm at this stage
variable: globalvariable1
comparison: =
value: this is the part I don't know how to put multiple text possibilities separated by |
