PHP PMS Read and Render - !!!! Realeased !!!!

[Doc]

PHP PMS Map Renderer v4
Fully written by Doc


What
This script will read a PMS map and output all of its data.
It can render a image of the PMS map with polygons, spawn points, colliders and waypoints.

If Image rendering options are set to 0 then you can use the normal textual data of teh map like title weather number of polygons and more.


Important
This script is under GPL. You may use this and/or edit lines, but MUST keep the copy right string visible in generated images.


The explanation is written in the readme.txt on how to use this.


There is about 600 lines so I did not post it here. (Tell me if 700 lines will fit here)
So I uploaded it to my site: Download


Fot those that just want a simple reader that gets you like the title and weather and stuff here is the code:

?>Those are the only things tha it will out put!

Version 4
- rewritten the whole code in class.
- modified, graphical objects loaded from image.
- added, easy otions and structure
- added, a lot of small things and stuff.

Version 3
- modified, orginized script to better performance
- modified, graphical objects simplified.

Version 2
- added, generating graphical spawns

Version 1
- basic read


Any questions or sugestion?

[urraka]

My sugestion: keep going, you made a cool job there

[mar77a]

teh selfish

[EnEsCe]

teh just give us the PHP script kthx

[DePhille]

Indeed, many people are looking for this, including me.
I can't see a valid reason why you wouldn't release the code. Some day or another, someone else will have the time and patience to write the same code and release it. Then he'll get more appreciation than you do, even if you found it first and yours is better than his.

The script is a good job, I know how it works. It's just stupid to write the script, knowing that someone else already did. I'd take away your work if I made it and published the code, so I'm leaving the publishing part up to you .

Grtz, DePhille

[Doc]

yeah I gues i should show the script.

Give me 1 or 2 days to referbish it. And write a "how to work it" thing and ill post it.



ps: after ill put in scenery option, i'll get to work on gradient triangle math (I started it befor but never got around to continue it. just needs time to outomate teh same lines.)

[DePhille]

Ahh, thanks.
We'll post suggestions once we have any.

Grtz, DePhille

[Doc]

I have released now. Please do read teh reasme.txt it will show you how to use it.
http://soldat.planets.gamespy.com/Files-view.php?f=php_pms_map_renderer_4.zip

[rainrider]

LOL and u want to add teh triangle-transformed textures dear imagefilledpolygon user : D

[Doc]

what are you talking about?

I can fill polygons wiht textures simple adding 2 lines and a small modification to the imagefunction

<snip> long off topic flame; keep it on topic, and keep with the rules of the forum --Chrisgbk</snip>

That what happands when i feel like i got a rude comment in 3:40 am.

[rainrider]

You just didn't show any custom image function in your code yet. That's why I laughed.

Also, polygon textures are stretched, rotated, deformed. You can't just load them and then create mask or something.

Even if you write your own pixel shader, it will be way too slow. Why?
Because you need to use many variables like pixel rgba, x, y, theta etc etc which need too be reparsed many times.
Because PHP is scripting language, you can't compile scripts; php script will always work way slower than compiled program.
Because imagefilledpolygon is placed in compiled library and it uses easy floodfill while you need to write your own function which will process large texture files, colorize them and furthermore set it's alpha.

If I were you, I'd write console program which would use OpenGL. OpenGL is well-optimized and it uses directly graphic card processor. That program would just draw everything and output screen in any format (even in your own), and you could run it in php script using system() (and if you'd use your own file format - load output file, set pixels [it will be always faster than slow processing all polys] and use imagepng or sth).

I don't want to be presuming or sth, I want to give you few advices.

@low:
ehh..

Any questions or sugestion?

gj with flippin burgers

[Doc]

Are you blind or just came out from under a rock?

This is for just displaying an image on a website.

IF YOU DONT LIKE THE IMAGE GENERATOR PART THEN JUST DONT SELECT IT AND USE THE NORMAL DATA THAT IS IN THE PMS.

[urraka]

Using system() or anything like that would be a really bad idea, cuz the good thing about this script is that it can be run on any website with php support.

[rainrider]

If you have enough money to buy host offering such webspace to share so many maps and its screens, no matters if it uses system() or not, you know what I mean.

Anyway you can always just download all maps at end of every day, then run rendering prog and just upload output screens. You can also write some program which would do everything automatically.

[blackdevil0742]

teh selfish

..and you're not? *cough* your server *cough*

Um yeah. Good job on this.

[mar77a]

what server? o-o

[Doc]

I alwasy did despise mar77a. 

[Thomas]

nice work!
i wanted to do it a few days ago, but you've been faster

[Doc]

I made teh scrip like in early 2006 you know.

And just know I made it public :p

[Coolio]

Nice, Thank You!!!
