hi i was a bit bored so i had an idea to compile a dll of community functions , mainly for ease of use but there might be a small speed increase .

anyway here is the beta
http://forum.thegamecreators.com/?m=forum_view&t=142264&b=18

just post there if you have got some functions worth putting in.

thanks chunks

Could you make a dll out of this function:

@ TheComet
I read the rems at the start of that function, and that's pretty smart actually, hehe, I'll remember some of that when coding similar things. (Especially the x*x being quicker than x^2)

Well, thank you!

I am having some real problems with the speed of the math functions in DBC. Mostly, I am talking about atan(), tan(), sin() and cos().

Is it possible to add these to a DLL? That would be great if it could boost the speed a bit...

And, if you are up for it, it would be really cool if you could add the rest of my object functions to a DLL. And I mean REALLY cool!

i did try your other object functions (prism and capsule) they came out a bit funky don`t know why they migh only work correct in db classic or i`ve done something wrong somewhere .

the maths functions might be in the c++ lib maths.h if they are you will most certainly get a boost and it should work with dbc.

also i don`t think most of these commands will work with dbc because i call the dbpro dlls and i don`t know how to do it with dbc .

iv`e added the distance function it seems to work ,will upload shortly .

it`s uploaded in the other thread if you want to try them i`ve added the maths commands too , not sure if they work properly

Is this dll mainly for DBP or DBC? Comet, I tested 20*20 vs 20^2 in Pro and 20^2 was actually faster.

i am making this for dbpro but some functions which dont call dbpro`s dlls will work with dbc eg ( the distance func , because i use the sqrt from math.h.).

if thats faster i will change that in my code , thanks.

Really? I ran some tests, and I got the opposite. Here is the code for DBC and DBP:



And here I edited the results into one image:



(All numbers are in milliseconds)

And, because I had nothing else to do, I even made a graph...

nice graph , i guess i wont change it .

@the comet did you test the maths commands out in the latest release ?

if so let us know how they go .

Yours is probably more accurate, I didn't use the FOR loops like you did, I just timed one calculation. What does the

for t=1 to 60
sync
next t

Do?

why would you want to sync 60 times before the main code ?

How strange ,unless it`s a dbc thing.

Oh, that is because the syncs jump a lot before the first 30 syncs... That means that for the purpose of calculating the first for t loop will take longer than it should, and the next for t loop takes the time it should. So to get the unsteadiness of the loops down, you run a loop about 60 times and sync.

It`s just a weird thing I noticed with DBC, is it like this in DBP?

@Chunks chunks

Downloading the update right now.

EDIT : Uhm, I am still a bit of a noob with DLL`s, even though I can use sparky`s. How do you call the functions?

@ the comet
if you are using dbp put the dll in user plugins and keywords in the keywords folder and thats it .


if you are using dbc put the dll in with your projects exe and use the call dll command.

you will have to search for the decorated names of the functions in the dll , just use notepad or dllexp viewer .




you`ve got to bear in mind that only your distance function and the maths commands i did what you requested will work with dbc.


EDIT: sorry your gonna have to wait for the distance func , i seem to have broken it ,anyways it shouldn`t take me long will put up a new release tonight.

EDIT2: It works fine in dbp ,just getting strange values calling the dll ,its probably something to do with having to cast a float to a dword to return it dbpro ,don`t know how it works for dbc ,will find out and let ya know.

I might actually say that this dll only supports dbpro ,but don`t fear when i get time in next few days i will make a special one with the commands you requested.

That makes sense, the program is probably still gathering resources and all that.
