Adding two variables together
I have a time variable that inputs a number (10 or 15 minutes) based on an object's state.
I have a second-time variable that operates the same way for another object.
Then I have a third variable to show the total of the two. However, when a user changes their answer on the object, the total time just keeps racking up instead of showing an accurate total.
How can I add the total of two variables together?
Without seeing exactly how you put it together, my guess is that you need a trigger to reset that total back to zero before the items are added each time.
Here is how it is set up.
As Ron mentioned, you need to reset the variable before adding to it.
Here's a good way to do that:
When either Total_Time or Total_Time2 changes, show a blank layer.
On that blank layer, have these triggers run when the timeline starts:
- Set calculation = 0
- Add Total_Time to calculation
- Add Total_Time2 to calculation
- Hide this layer [Note: you could also have this run when the timeline ends, and use a really short timeline.]
