Help: Simple Number Counter

The <simplenumber> control template won't work, it does not have the code to use the multiple <source> and <op> properties. You need to use the <number_linked> control template.

Thats it! It worked! Thank you!

Also, is there any way to do some slightly more complex operations, like Attribute*2 + attribute2*3?

Also, is there any way to do some slightly more complex operations, like Attribute*2 + attribute2*3?

The code steps through each <source> entry in order and applies the <op> mathematical function using the value of the database field pointed to by <source><name>. Supported <op> mathematical functions are: +, -, *, - and neg+ (only add the value of the source if it is negative).

So, from this, you can't do "Something * 2" unless you have a database field containing "2" that you can point the source to. Plus, the process doesn't follow the mathematics BODMAS order for processing, so you can't do "Attribute*2 + attribute2*3".

If you want to do mathematical calculations like this then you'll probably have to look at writing the code in LUA and using onUpdate event handlers against the sources to trigger an update in the target field. See "Handler functions" here: https://www.fantasygrounds.com/modguide/scripting.xcp Or have intermediate <number_linked> fields that store their result in the database and then use these database fields in the final result. e.g. one <number_linked> field to calculate Attribute*2, one <number_linked> to calculate attribute2*3 and a final <number_linked> field to add the two together. You can make the first two fields invisible so they aren't shown on the GUI. But this would be quite a complex approach to something that could be covered in LUA using handler functions.
