yep another question.
Im makeing a game where you wander the desert along the noncopyrighted "Silk path".
I have a waterlevel and it is a textnumber.
Now when the actor is created it creates a timer and when the timer goes off its supposed to subract 2.
this is the code i use
waterlevel.textNumber = waterlevel.textNumber -= 2;
But when i do that the textnumber becomes -2.
I tried to correct the code, but then it equals -1.
is there something wrong with the code?

Try this:
waterlevel.textnumber = waterlevel.textnumber - 2;
I think that should work.

i still came up as -1.
Heres the exact thing i do.
Create actor/ creatimer
timer
waterlevel, periodic, 10000 ms, forever

Timer / script editor
waterlevel.textNumber = waterlevel.textNumber -=2;
Then it comes up as -2

When i did your approach it came up as
-1;

Huh... Is waterlevel a variable or an actor?

[trippola77]

its an actor

This is unnecessary:

Code: Select all

waterlevel.textNumber = waterlevel.textNumber -=2;

You should be able to do

Code: Select all

waterlevel.textNumber -=2;

or

Code: Select all

waterlevel.textNumber = waterlevel.textNumber - 2;
