Struggling with adding parameter values together
Happy holidays, first of all - none of this is urgent, so don't worry about rushing to help with my question in the upcoming few days!
I'm running into a bit of a problem with using parameters, and hopefully I'm just missing out on something obvious; is there a way for me to add a Global Variable parameter to another value? As far as I can tell, I'm only able to add Integers and Floats to Global Variables, and not add them together.
If this is unclear, here's a more detailed explanation of what I'm trying to achieve;
I've created an actionlist called "DiceRoll", with three parameters; Attribute, Skill, (Both Global Variables, both Floats) and Target (a Float). In the prototype I'm working on, whenever the player performs an action that requires a dice roll, the Actionlist is triggered.
For example, let's say the player interacts with a Hotspot called "Broken Car", and one of the Interaction Icons is "Repair". The player chooses this interaction, and the Hotspot actionlist, in turn, runs "DiceRoll" with the following parameters;
1. Attribute set to Dexterity (Global Variable, Float)
2. Skill set to Repair (Global Variable, Float)
3. Target set to 8 (Manually as a Float parameter in the Broken Car interaction ActionList)
4. Finally, at the start of "DiceRoll", a random number is generated. (RN, also a Float)
I'd like to add both Attribute and Skill to that number before comparing it to Target, (RN + Attribute + Skill >= Target) but I'm struggling to find a way to do so - the only parameter I seem to be able to add is Target, the Float. Is there a way to add Global Variable parameters to each other, or extract the value in the parameters and random number to add to a single "Total" variable? Or is there a much simpler way of doing this that I'm missing?
Howdy, Stranger!

You'd need to extract them, as AC won't be aware of exactly what type of variable is assigned to a "Global Variable" parameter.
One way to approach this would be to create a pair of Global Float variables that act as "temp variables". You can transfer the parameter values to these temporary variables using the Variable: Copy Action, and then sum them using Variable: Set.
I'm able to copy the parameters to Global Floats, but I'm still not able to add them together or to a single "Total" Global Variable. Right now I'm working around it with some custom code, but I figured I'd ask in case I was missing something!
The Variable: Set Action has a "Formula" option when dealing with Float and Integer variables. Inside this, you can use variable tokens to add multiple variables together.
For example:
That makes sense - I was trying to add them by name or as you would in code, but didn't try [var:X]! Much appreciated, everything's working fine now!
