functions to access list of nodes added or removed since last world update.

[danni.coy]

This is something that has been perculating in my head for a while now.

I have been doing a lot of editor plugins which are very specific to things I have in our world script. This means that I have a lot of calls from the editor space to the world space to take a account of when nodes are added or removed.

It would a lot easier to build generalised editor plugins if I could do something like the following in the world script.

 

 

int num_nodes = -1;
 
void update() {
    if (engine.editor.isLoaded() && engine.editor.getNumNodes() != num_nodes) {
         forloop (int i = 0; engine.editor.getNumNewNodes()) { addNode(engine.editor.getAddedNode(i); }
         forloop (int i = 0; engine.editor.getNumRemovedNodes()) {removeNode(engine.editor.getRemovedNode(i);}
         num_nodes = engine.editor.getNumNodes();
    }

 

alternatively if the world script could define the following hook functions at the top level. (like init and update)
 

 

void nodes_added() {
    ....
void nodes_removed() {
   ....

Hi Danny!

 

Take my apologies for the late reply! Could you please write usage code so we'll clearly understand what exactly you're trying to solve and why do you need such callbacks?
