The Playground Editor is a program with which you can create playing fields for games. To do this, you specify a size for the playing field, import graphics and place these graphics on a generated grid.

You can define different backgrounds, objects and switches (example: background = meadow, object = tree, switch = treasure). Once you have created your playing field, it can be saved as a project. This makes subsequent editing easier.

The saved project can be exported. The exported playing field is a text file with the entries of the playing field and the associated graphics. If you want to incorporate this into a game, you have to read out the text file and use the read out data to generate the playing field.

In the text file, 3 numbers per field of the playing field are separated by a colon. Each field is marked with a straight vertical line | separated:

The first number is the number for the background, the second for the item, and the third is the switch.

This makes the generation of playing fields much easier. Because, unlike in most common forms with w for wall, p for player and spaces for empty space, you can plan a complete world here. The switch can stand for many things, e.g. for a random function for opponents, finding objects or the destination of a level.

In the editor you can insert a comment for each object, which provides a better overview, especially with the switches.

Installation

Since the Playground Editor is not part of the Haiku standard installation, it must be installed from an external source.

To integrate the installation source into HaikuDeport enter the following command line in the terminal:

BeSly 32bit

BeSly 64bit

Then open HaikuDepot and update the repository server via "refresh repositories" in the HaikuDepot menu.

After the update has been completed, the packages from our repository server are also listed in the package lists.

Search for PlaygroundEditor and install it.

Create a new project

In the start menu of the program select "new project".

In the next window you define the size of the desired playing field (vertical fields and horizontal fields) and its name.

After confirming this information, the playing field will be created. This is initially a grid with the desired number of fields.

Insert graphics

Now go to "Tiles" to add playing field graphics (tilesets).

To add graphics here, search in the left directory list for the corresponding graphic and add it to the desired area (backgrounds to "Backgrounds", objects to "Objects").

After adding the tilesets, go back to the editor. The tilesets that have been added are now displayed here.

Painting the playing field

There are three lists in the right area of the editor. One for the backgrounds, one for the objects and one for the switches.

To paint a playing field, select one of the graphics listed and paint it on the editor field on the grid area by pressing the left mouse button.

Descriptions of the tilesets

To ensure a better overview, every background, every object and every switch can be given a description. To do this, select one of the entries and use the right mouse button to select the "Add Description" option. A description can then be inserted and added in the upper right input field.

Export playing field

To export the playing field go to "Export".

There are several ways to export the playing field. The playing field can be exported in whole or in part. To do this, select the appropriate storage option and press export.

The different options allow different processing of the playing field file. Everyone has different approaches and logic in programming. Therefore you can create a classic playing field here which is simple and simple, or you can use all functions and use the extensive range of functions.

The exported playing field is output as a text file.

You can also export a screenshot of the playing field when exporting. This makes programming easier because you can see what is where better without looking at numbers and letters.

In some programs is it possible that copied informationen from clipboard goes automaticly into a textedit or textcontrol.

In this code is a example to get the informationen from the clipboard automaticly.

#!/boot/home/config/bin/yab
 window open 400,100 to 600,300, "Clipboard_test", "Clipboard_test" dim msg$(1)
 while(not finished)
    n = token(message$, msg$(), ":|")
    for i = 1 to n
    if (CLIPBOARD PASTE$="") then
    else
        draw flush "Clipboard_test"
        draw text 10,10, CLIPBOARD PASTE$, "Clipboard_test"
    endif
    if(instr(msg$(i), "Quit")) finished = true
    next i
wend

Sometimes i have the problem that an array is not sorted. So I wrote a little subroutine that solves exactly this problem. This example is for sorting numbers. The example at the end is for strings.

dim zahlen(10)

zahlen(1)=10
zahlen(2)=0.10
zahlen(3)=5
zahlen(4)=3
zahlen(5)=8
zahlen(6)=55
zahlen(7)=10777
zahlen(8)=22
zahlen(9)=0.0001
zahlen(10)=1034

sorting_array(zahlen(),"desc")

sub sorting_array(zahlen(),order$)
	// Asc or DESC
	if (order$="asc") then
		for k =1 to arraysize(zahlen(),1)
			for i =1 to arraysize(zahlen(),1)
				if (i=arraysize(zahlen(),1)) then
					break
				endif
				if (zahlen(i) > zahlen(i+1) ) then
					temp = zahlen(i)
					zahlen(i) = zahlen(i + 1)
					zahlen(i + 1) = temp	
				endif
			next i
		next k
	elseif (order$="desc") then
		for k =1 to arraysize(zahlen(),1)
			for i =1 to arraysize(zahlen(),1)
				if (i=arraysize(zahlen(),1)) then
						break
				endif
				if (zahlen(i) < zahlen(i+1) ) then
					temp = zahlen(i)
					zahlen(i) = zahlen(i + 1)
					zahlen(i + 1) = temp
				endif
			next i
		next k
	endif
end sub
for i=1 to arraysize(zahlen(),1)
	print zahlen(i)
next i

This example is for strings. It is sorting upper case frist, then lower case by option asc. By option desc the upper case strings are at the end.

dim text$(10)

text$(1)="gert"
text$(2)="google"
text$(3)="Firefox"
text$(4)="Android"
text$(5)="ZigBee"
text$(6)="Hubert"
text$(7)="Hello"
text$(8)="Alfred"
text$(9)="Batman"
text$(10)="Robin"

sorting_array(text$(),"asc")

sub sorting_array(text$(),order$)
	// Asc or DESC
	if (order$="asc") then
		for k =1 to arraysize(text$(),1)
			for i =1 to arraysize(text$(),1)
				if (i=arraysize(text$(),1)) then
					break
				endif
				if (text$(i) > text$(i+1) ) then
					temp$ = text$(i)
					text$(i) = text$(i + 1)
					text$(i + 1) = temp$	
				endif
			next i
		next k
	elseif (order$="desc") then
		for k =1 to arraysize(text$(),1)
			for i =1 to arraysize(text$(),1)
				if (i=arraysize(text$(),1)) then
					break
				endif
				if (text$(i) < text$(i+1) ) then
					temp$ = text$(i)
					text$(i) = text$(i + 1)
					text$(i + 1) = temp$	
				endif
			next i
		next k
	endif
end sub
for i=1 to arraysize(text$(),1)
	print text$(i)
next i
