Sprites

[maiku]

!!!

I can't figure what a sprite is, let alone how to use it.....I'm a total noob

I believe a sprite is an image that I use in my program, like the main character, and if I'm wrong, please correct me!

If I'm right, then someone please tell me what command I use to do this, because the turing help guide isn't exactly very specific...I need an example, or a fake example...
Please???

Sprites only work in versons of turing less then 4.0.1 or greater then 4.0.4c. And even in 4.0.5 they are ify.

What they are is an image witch can be moved with out destoying the backgorund image. However this is not the best way to do this and in the new versons of turing you should be using View.Update and offscreen graphicsks mode to do animation.

For more information on both subjects please use the search function or look threw the tutorals. Or you could post your questions here, i guses =p.

Sprites are usually the graphics used for different "people" IE: the characters you control/interact with.. Often times you get a sprite "sheet" which has different positions for each possible move the user would make..

EXAMPLE:
http://www.northcastle.co.uk/archive/vault/sprites/link2.gif

In Turing the sprite functions give you control over linking these images and then depending on a getch statement you can move them around..

I personally do not use the sprite functions.. Thats not how I started my current project and I had no intention of switching over.

Test:

THE BELOW CODE IS SLOPPY:
One reason is your not releasing pictures your done with.. so after 1000 steps your program will crash. Also there are a number other reasons why this is sloppy but for the sake of easy to follow code I like it. You will need 12 pictures total.

3 Different pictures for him walking UP, DOWN, LEFT, RIGHT (Think Zelda)
Each picture should be named as such:
UP1.bmp
UP2.bmp
UP3.bmp
DOWN1.bmp
ect...

Goodluck

code:

View.Set ("offscreenonly") setscreen ("graphics:vga") setscreen ("nocursor") var keypress : string (1) var spriteID := Pic.FileNew ("RIGHT1.bmp") var corX, corY : int := 220 var StepCount : int := 1 Pic.Draw (spriteID, 220, 220, picMerge) loop         getch (keypress)  % MAIN ACTION GETCH COMMAND                 if (keypress) = (KEY_UP_ARROW) then             corY := corY + 5             if StepCount = 1 then                 Pic.Free (spriteID)                 spriteID := Pic.FileNew ("UP1.bmp")                 StepCount := StepCount + 1             elsif StepCount = 2 then                 Pic.Free (spriteID)                 spriteID := Pic.FileNew ("UP2.bmp")                 StepCount := StepCount + 1             else                 Pic.Free (spriteID)                 spriteID := Pic.FileNew ("UP3.bmp")                 StepCount := 1             end if         elsif (keypress) = (KEY_RIGHT_ARROW) then         %Key Right Arrow             corX := corX + 5             if StepCount = 1 then                 Pic.Free (spriteID)                 spriteID := Pic.FileNew ("RIGHT1.bmp")                 StepCount := StepCount + 1             elsif StepCount = 2 then                 Pic.Free (spriteID)                 spriteID := Pic.FileNew ("RIGHT2.bmp")                 StepCount := StepCount + 1             else                 Pic.Free (spriteID)                 spriteID := Pic.FileNew ("RIGHT3.bmp")                 StepCount := 1             end if         elsif (keypress) = (KEY_LEFT_ARROW) then         %Key Left Arrow             corX := corX - 5             if StepCount = 1 then                 Pic.Free (spriteID)                 spriteID := Pic.FileNew ("LEFT1.bmp")                 StepCount := StepCount + 1             elsif StepCount = 2 then                 Pic.Free (spriteID)                 spriteID := Pic.FileNew ("LEFT2.bmp")                 StepCount := StepCount + 1             else                 Pic.Free (spriteID)                 spriteID := Pic.FileNew ("LEFT3.bmp")                 StepCount := 1             end if         elsif (keypress) = (KEY_DOWN_ARROW) then         %Key Down Arrow             corY := corY - 5             if StepCount = 1 then                 Pic.Free (spriteID)                 spriteID := Pic.FileNew ("DOWN1.bmp")                 StepCount := StepCount + 1             elsif StepCount = 2 then                 Pic.Free (spriteID)                 spriteID := Pic.FileNew ("DOWN2.bmp")                 StepCount := StepCount + 1             else                 Pic.Free (spriteID)                 spriteID := Pic.FileNew ("DOWN3.bmp")                 StepCount := 1             end if         end if                 %DEBUG:::         color (3)         colorback (255)         cls         Pic.Draw (spriteID, corX, corY, picMerge) % DRAW SPRITE         View.Update end loop

Thanks for the info guys

If you think I'm kinda dumb, you'd be guessing right....

I use Turing 4.0.5 so sprites hould work, but I'm still a little confused

Any more info would help but I think I got it

THANKS!

[[Gandalf]]

Sprites in Turing 4.0.5 are only either using the Pic module, or else using a third party library, like DanSprite or BacchusSprite. You do not have the ability to use the Sprite module, but sprite graphics manipulation is quite possible using the Pic module, as long as you redraw the background at every frame.

ok.....

This kinda helped......It took me this long to figure it all out, and I noticed that I'm not getting any good information, everyone si just complaining that I shouldn't use sprites......But honestly, It's the way I want to do it.....So ANYONE PLEASE TELL ME HOW!!!!!

I think I'm doing it right, but i got mad and deleted my code.....the problem was that my sprites weren't appearing

Help anyone???

[Imm0rtal]

I would have to see your source code to tell you what was wrong with it.. OH YEA! you deleted it.. smooooth.

My source code would work find and it is reccomended you use it. You asked for our help and we gave it to you. If it is too complicated to copy and paste my source code into turing.. Get 9 pictures with the proper names. Then perhaps your in the wrong forum.

Sorry but we can't make it any simpler..

[Imm0rtal]

Make that 12 pictures

[rizzix]

Imm0rtal easy on the double post.

[maiku]

I am thankful for your help, and no, its not too complicated to copy your code into turing, but i have almost the exact same program, but a bit smoother

And that last post really made no sense what so ever........

But thats anyways

[maiku]

Here's my coding program, zipped

[Imm0rtal]

I got an error when running the program.

[[Gandalf]]

I don't. And I don't see the problem, the code works fine on both Turing 4.0.5 and Turing 4.1. There are many ways I would suggest improving the code (ie. split it up into procedures/functions, only use one delay in the loop, etc) but it seems to work for your purposes. You must ask a question first before getting an answer.

[maiku]

The program does work, just make sure you have the folder 'chrono' in the same location as the .t file

I was wondering if someone could change my coding, or redo my coding, so that It is done with the Sprite module, and not Pic

Oh, and there needs to be a lot of delays, just because of the way the images are set up. The character (chrono) takes a step, but he always returns to a standing still position facing the way that he just moved

[Imm0rtal]

You should get rid of the delays... they make a slight pause everytime you press a key that is very annoying..

also if you want him to face the same way after you move him.. that shouldn't be very difficult at all.
