Perhaps not the root problem given your description, but shouldn't these:
...be these:
?

void my_wait_func(var) = wait; //save pointer of wait in my_wait_func

#define wait(i) do{ diag("waiting\n"); my_wait_func(i); } while(0)

[edit]
Techmuc ninja'd me with a solution x)

Hehehe, no he didnt.

I tried that before, and again with TechMuch's exact code,and get a syntax error on
AND Ive tried with an empty function pointer and engine_getscript in the start of main, but it return NULL.
It seems 'wait' is a function, not a 'script'....

Next!

Nice try though...

[EDIT] Check your post for typo's please Jibb. What you ask makes no sense to me...

It makes sense what he writes, otherwise there would be an extra ';' at the end which the Lite-C compiler doesn't really like.

About wait(), I'm not even sure if its a real function anyway, since it returns to the caller of the function that calls wait and does other quite interesting stuff.

"since it returns to the caller of the function that calls wait"
Doesn't every function return to the function that called it? I don't understand this sentence...

Hmmm.. Either JibbSmart sneakily editied his post befor JustSid saw it,
or Im going blind...

Yes Jibb, you are correct. The ';' characters in the defines WERE misplaced.
Damn typos. Thanks for pointing that out, it may have bitten me later.

But, as you say, it doesnt help with my root problem.

[EDIT] Time to increase my font size AGAIN! Sorry Jibb!

Nope No edits.

the best way would be to hook the engine wait call. doing this it would be possible to execute user defined script within any wait call (any script you need - at least if the script does not start a wait call again ).

If you really need such a plugin we can talk about this.

NEED is too strong a word.
Its a de-bugging tool, so I feel a plugin is more work than its worth.

But as a point of note... its been a while since 'the developer' posted
any comments in this thread...
