HGE Wrapper tip #1,#1A (update 12 JUN 2008)

Rook Zimbabwe · Post by **Rook Zimbabwe** » Wed Jun 11, 2008 8:54 pm

I have just now started poking into the HGE wrapper located (for DL purposes) on thread:

http://www.purebasic.fr/english/viewtop ... ge+wrapper

And I have chopped together a PLINKO style starter to display how to set up objects and utilize them...

This example meerly shows how to create a series of sprites that you can bounce boxes off of...

I had to redo the includes because they kept giving me LINK errors as someone seems to think we are all going to dump every library in a folder called /include/Libraries/PBLIBS/... etc!!!

If you need help on that, post I will attempt to remember what I did and if I can't I will post the includes I modified.

Code: Select all

; adapted from Tutorial 9 with the boxes and chain bridge
; just wanted to see how it works - Rook Zimbabwe (Ralph Dunn)
; cannot seem to set up walls!

OK tip 1A... This lib needs some work... (BYO where are you?)

The following code is a modification. I used two images you can DL below the code... I just pulled them out of the same directory since this is a incredibly basic example!

Now you press LEFT mouse to fire the ball... If you press too quickly you will overwhelm the program... I know some of you are oging to do that anyway thinking this is some kind of PACHINKO machine!!!

Code: Select all

; adapted from Tutorial 9 with the boxes and chain bridge
; just wanted to see how it works - Rook Zimbabwe (Ralph Dunn)
; added a weird trigger that works on rebound.
; cannot get the bumper to actually be an angle

Have fun...

I must say that HGE seems a bit limited and very blocky... I am rather disappointed in it now!

Perhaps it is me... But it seems your entire program is basically just sending messages to HGE to do things. You have so little control it is funny!

Please add the precompiled examples for downloading.

Hey, Rook. The examples are looking good so far. I can't download external sites files at work right now but I'll try to find my way around it.

Rook Zimbabwe · Post by **Rook Zimbabwe** » Thu Jun 12, 2008 5:30 pm

I would truly love to post the compiled examples. I will post a ZIP file. I wish HGE would let you include the graphics in your program. This is one of the reasons I am dissappointed in it!

You can just include the images inside the exe .. VERY nice btw!!

I am currently attempting to figure out the MAZE GAME example... I see how it reads the map... but I cannot understand how it reads the map... Nor can I increase the size of the game yet.

{SIGH}

I am attempting, first, to increase the output of the MAZE GAME to 800 X 600... Then I will attack map format.

Rook Zimbabwe · Post by **Rook Zimbabwe** » Fri Jun 13, 2008 9:17 pm

AFAIK the numbers in the map.dat file are the following:
401 301 (dimension of map)
079 placeholder

all other numbers refer to 32 X 32 tiles in the map.png image... 017 for instance is the START square and 001 for the animated EXIT

Looks like it is just one long row of info... read control by the first two numbers in the map.

Too simple really...

@Rook
You are right with the Maze-Example. I converted it from C without any tranlation or comments. It was a very easy format.
BTW:If you look at the HGE-Fotum there are a Tile-Editor coming (if they finish them..).

And thanks for the great examples !

I have been waiting for that mapeditor for almost 2 years now. Time to crunch my own!

Hurga · Post by **Hurga** » Tue Jun 17, 2008 7:44 am

If you makle a map editor, I´ll consider using the HGE...

byo · Post by **byo** » Tue Jun 17, 2008 5:04 pm

Very nice examples.

How complete is the HGE port?

Hi byo - it is not a port - it is only a wrapper.
So HGE is stable as the released version. The wrapper is nearly complete to cover HGE. But the Physics-Part (Box2D) is not complete - maybe i spend some time to add more wrapped functions.

I thinking about adding more extension or ability for extensions. special for GUI-Elements.
