[Pipmak-Users] Node images

[Urs H. <ur...@an...>]

Hi

Is it possible to change the images of nodes? Consider for example a
node with

cubic { "1.jpeg", "2.jpeg", "3.jpeg", "4.jpeg", "5.jpeg", "6.jpeg" }

I am in the situation, that the lighting of my game world can change.
The functionality of all nodes is independent of the lighting. However,
changing the lighting changes the images of all sides of all cubic
nodes.
So it would be good if I could do something like

cubic { 
state.light .. "1.jpeg", 
state.light .. "2.jpeg", 
state.light .. "3.jpeg",
...

Is this possible?

Apparently you haven't tried it? Yes, this is possible. You can use any 
Lua expression that evaluates to a string at any place where a string is 
expected (and likewise for all other data types). Don't forget that 
"cubic" is just a function and "{...}" is just one way of specifying a 
table, so, assuming that state.light is a boolean value, you could also 
write something like

   cubic(state.light and {"1l.jpeg", ... } or {"1d.jpeg", ... })

(the parentheses are necessary if the opening brace doesn't immediately 
follow "cubic")

or

   if state.light then
     cubic {"1l.jpeg", ... }
   else
     cubix {"1d.jpeg", ... }
   end

However, I wouldn't really call that "changing the node images", since 
it only takes effect when the node is loaded. If you want the change to 
happen while that node is displayed, you must reload it 
(pipmak.gotonode(pipmak.getcurrentnode())). There's currently no way of 
changing the node background images "on the fly".
