How to use images in Turing


You can load 3 different types of pictures in Turing. They are PCX, BMP and TIM.


1st you need to load the image into Turing's memory:

var varname :int := Pic.FileNew ("filename")


Ex.

code:

%for a file that is in the same dir as your Turing code                                                                                                                          var mypic :int := Pic.FileNew ("coolpic.bmp")

or

code:

%to specify the exact location of this file        var mypic :int:= Pic.FileNew ("c:\turing\mygame\coolpic.bmp")

2nd you need to show the picture and set it's location on the screen

Pic.Draw (picID, x, y, mode)


Ex.

%to draw the picture in the center of the screen with no mode
Pic.Draw (mypic, maxx div 2, maxy div 2, 0)


The modes:

picCopy This draws the picture on top of what was underneath, obscuring it completely.

picXOR This draws the picture XORing it with the background.

picMerge This draws the picture like picCopy except that any occurrence of the background color in the picture is not drawn to the screen.

picUnderMerge This draws the picture, but only where the background color was displayed underneath it


If you want to get rid of the picture after you have drawn it on the screen use cls and to get it out of the memory of the computer use Pic.Free (mypic).


Example of a program that uses pics:

code:

%program to show a logo picture                 var mypic :int := Pic.FileNew ("coolpic.bmp")                 Pic.Draw (mypic, maxx div 2, maxy div 2, 0)                                 delay (2000)                 cls                 Pic.Free (mypic)

this was one of the 1st turealrs i made, i dont think i did a good job on it but i figered why not post. so here it is...

turing 4.x also supports .jpg format. And you can also hope for .gif support in about 4-5 years from now.

*sniff* how i wished i found this forum earlier..i've been struggling for 2 days to find out howt o do that in turing..*sniff*

[Vicous]

on a side note, what is the code for changing the window size, I know it has something to do with setscreen

[Tony]

View.Set("graphics:length;height")

as in View.Set("graphics:400;100")

[Vicous]

wha? whats the dif between view.set and setscreen?

[Tony]

no difference... you can use ether one you like.

can you elaborate on a few things, such as how to set which background color, and what XORing means?

I figured picXor was just some guys at UofT being leet.

don't hax0r my picX0r!

ooooh yea!

[Tony]

someone beeing playing too much counter-stike

its a good game though 8)

[Tubs]

rofl thats good

its not just in cs, that kind of language is on every internet game

btw cs sucks compared to mohaa bf1942 etc etc

[Asok]

I have to agree, in bf1942 you get to run people over in viechles! *remembers tribes2*

*beep beep*
whoops

[Vicous]

hate to be the one to break up this converstation (Counterstrike sounds familiar but I can't pin it down right now) but I kinda want the answer

[Asok]

k, all the pic options have to do with picture layering on top of eachother

picMerge will set it so that the color that matches the background is actually transparents so you can see images underneath

picCopy place the image on top of allready drawn images.

picXor inverts the color that is different than the background when a picture is touching it.

picUnderMerge sends the picture to the back so that other images that were drawn before it are still above it.

EDIT: oh and to set the background color is:

code:

colorback(color)

where the parameter is replaced with the actual color you want. (the Candian spelling of "colour" works too.)

[Vicous]

what is this candian place and do they have candy?

sorry, that was just too tempting, thank you for answering my questions and giving me a reason to laugh
