Just curious if there is a way to average stats together in order to make an entirely new stat. Then display it in the stat screen. Say for instance I have the overarching stat of ship health, but I want to break it down into bridge integrity, aft section integrity, etc. Could I average all the parts of the ship into a new stat which shows the overall ship health? ---

Add all the “parts” together and then divide by the total number of parts to get the combined average. Do this calculation whenever any of the parts has a change in value to keep the combined average always up to date. ---

In startup you would do something like this: ``` *create bridge_left 20 *create bridge_right 30 *create bridge_integrity 0 *set bridge_integrity (bridge_left + bridge_right) / 2 ``` And then in stat: ``` *stat_chart text bridge_left Bridge Left text bridge_right Bridge Right text bridge_integrity Bridge Integrity ``` ---

tried what you said but I got this error line 41: Invalid expression at char 20, expected closing parenthesis, was: OPERATOR [+] ---

It is definitely referring to the \*set bridge\_integrity (bridge\_left + bridge\_right) / 2 ---

Try \*set bridge\_integrity ((bridge\_left) + (bridge\_right))/2 ---

Whereas this will work as Nocturnal\_Stillness has written, depending on the number of variables you add, you could end up with a very long decimal place after your answer. Eg: \*set bridge\_left 90 \*set bridge\_right 100 \*set bridge\_middle 100 Set bridge\_integrity (((bridge\_left)+(bridge\_right))+(bridge\_middle))/3 This would set bridge\_integrity as 290/3 = 96.66666666666666666666666666666 There is a long winded way to round this up/down but is there a choicescipt command to do that? Is there a command \*round ? ---

@andymwhy Just like so: Set bridge\_integrity round((((bridge\_left)+(bridge\_right))+(bridge\_middle))/3) Note the extra parentheses to round the whole sum. ---

Oh, now _that_ there is some useful knowledge. Thanks, @Vendetta - been wondering about rounding for a while, don’t know why I didn’t ask the forums… ---

@Havenstone It’s just something I had to figure out ages ago, as Vendetta’s character finances used to produce values not entirely unlike andy’s figure there… \*cough\* I have to agree with your sentiment though – I often don’t even think to ask here, and instead subject myself to an awful lot of hair-pulling, teeth-gnashing and cat-kicking… (only j/k on the last bit, honest!).
