Hi

I have a number of panels each with layers in my script. I want to know if you can move both back and forward between panels using an 'if' condition or whether the panels will appear sequentially irrespective of the condition based on their layer value? e.g. Panel 2 layer value is 50 and Panel 5 layer value is 20. Panels 1, 3 and 4 would have layer values of 60, 40 and 30 respectively.

In the first example panel 2 is reset and panel 5 appears based on the if condition e.g.

if (some condition is true)
reset (Xpanel_2, SHOW) && set (Xpanel_5)


In the second example panel 5 is reset and panel 2 appears.

if (some condition is true)
reset (Xpanel_5, SHOW) && set (Xpanel_2)

Is there the possibility that this would work for a while and then the system would get confused and default to running panels sequentially e.g. 1 then 2 then 3 then 4 then 5 simply based on their layer values and ignore the if condition? Perhaps the layers are not necessary?

I am sorry but I don't understand your question at all, can you try to state it again precisely in other words?

The system does not get "confused", no matter what you do or how long your code/ while loop is running, provided that you don't mess up the code on your side.
You can set and reset the SHOW (and any other) flag as often as you like, you are just changing the value of a panel struct's number/ member. It does not get rendered immediately but at the end of the frame after all script execution and world rendering.
You can use the function layer_sort(void* element, var layer) to change the layer of any screen element at runtime.
