Function references

[sahara-min]

I'm having a lot of fun playing around with F4NS so far! Here is a little feature suggestion:
It would be useful to be able to store references to functions in variables/arrays/structs or pass them as arguments to other functions.
Imagine being able to do something like this:

array entity[100] = [ .position = { 0, 0 }, .behavior = noBehavior ]


// Assign functions to .behavior on entities
entity[0].behavior = playerBehavior
entity[1].behavior = enemyBehavior
entity[2].behavior = enemyBehavior
entity[3].behavior = enemyBehavior


loop
    updateEntities()
    update()
repeat


function updateEntities()
    for i = 0 to 100 loop
        entity[i].behavior(i) // Call the function assigned to .behavior
    repeat
return void


function noBehavior(i)
    // Do nothing
return void


function playerBehavior(i)
    // Do player stuff for entity[i]
return void


function enemyBehavior(i)
    // Do enemy stuff for entity[i]
return void

I believe they are in the process of being able to call functions in this manner.

@Discostew can you let me know where you heard this please so I can lookup the info. Thanks.

This should do the trick, however there are some limitations:

The timer is set to 0 delay and unlimited repeats, so the timers must be stopped inside their function.
The function will be called once because the interval is set to 0 seconds, so keep that in mind when implementing.
Let me know if you have any more questions :)

@Jaywalker That's pretty clever! Still would be nice to have proper function references though :)
