Hullo all. Smiley

I've created a very simple plugin for Dark Basic Professional to help out with timer based movements. It's not advanced at all. It's just intended to be used by those people who don't want to setup a timer based movement system for every project they create - hence I made it (mainly for myself).

Here's the readme file.
Quote: "Timing Plugin v1.0
-------------------------------------------------
This is a simple plugin to help control
timing in Dark Basic Pro. This allows you to
more easily implement timer based movement which
allows for quicker development times.

I made this to help me out because I was
making a bunch of really small projects to test
out some other plugins. Each one would spin an
object around in a timer based fashion to ensure
the demo runs just as smoothly across all
computers.

Commands
-------------------------------------------------
setTimerDivisor divisor#
Sets the divisor for the returned time. The
default value is 30.0.

divisor# = getTimerDivisor()
Gets the divisor set by setTimerDivisor.

updateTimer
Updates the timer. This updates the return
value in getTimer(). Call by SYNC.

getTimer
Retrieve's the scalar timer value. The return
value can be multiplied by a 1.0 based
scalar value to keep proportionally based
timing. For example, if you want an object to
move twice as fast as normal, then multiply
this value by 2.0. If you want it to move half
as fast, multiply this value by 0.5.

Installation
-------------------------------------------------
Copy the file "Timing.dll" to the
Compilerplugins-user directory in the main DBPro
installation directory. Copy the file "timer.ini"
to the Editorkeywords directory in the main
DBPro installation directory. Restart your IDE &
it'll be ready to be used."


It can be downloaded from my forums, here.

Hopefully some of the newcomers and demo writers will find this useful.

Also, here's some example code as to how to use it:

Does this use something more higher resolution than the standard DBPro timer() function?

I'm thinking like the matrix utility's hitimer() function.

I'm not a real programmer but I play one with DBPro!

I can make a higher resolution timer if you like, it does it based on milliseconds - I don't see a problem with that though since most games only need to run smoothly based on 30 FPS which is much more easily done with milliseconds.

However, I can make it work like that for ya.

Thanks.

@Guido Italy
I'll repost here what I said at the other forums.

Hi naota, you probably already know this but I figured I would explain what I mean. The DBPro timer() command does not use a high resolution timer. It uses the "windows timer", which seldom reports anything lower than 8 or 15ms in passing. Sometimes it reports things in skips and spurts of 0s and 15-16s. At least that's what it does in my experience...

A high resolution timer can still report in milliseconds, but reports much more accurately when a smaller timestep is encountered. So I guess my question is are you tapping into the DBPro timer() command? Or do you have your own raw C/C++ timer function you're using?

I'm using the Windows GetTickCount() command - Not the DBPro timer() command. I can, however, use the QueryPerformanceCounter~ based commands to retrieve higher resolution tick counts.

I won't do it though, unless someone requests it.

i just tested the example and for me its
divisor = 15.0 is the same speed as sync rate 60 (with turning 1 unit every frame)
and divisor = 10.0 is same as sync rate 100 ...

how would i find out the divisor for setting it to e.g. 30 fps?

30 seems to be right.

If you mean mathematically, if the divisor is 30.0 resulting in 30.0 fps then that's equal to 1. With a divisor of 15.0 resulting in 60.0 fps then that's equal to 2. I'm not that good at math though, so I *think* something like this:


The maths of the function of above when given 60.0 as fps# the returned divisor is 15.0. So that should be correct. I've only tested the function on an fps of 60.0 though.

Cheers,

yeah thats basically
30/fps *30 = 900/fps
and for 100 it returns 9, and i got 10 in my tests so that should theoretically work
thanks

I think I'll incorporate that function in the next version (1.1).
I think I'll improve the timing too, I guess (Higher resolution) - no one actually requested it, but why not?


In order to get more popularity at my forums, the next version (1.1) will be uploaded there for 14 days, then uploaded to these forums. The reason being - well come on, who doesn't want people at their forums?
