scrolling and tilemapping tutorial?!?!

[saintrunner]

So after finally learning tilemapping, I am finding I can't figure out how to implement scrolling! I wanted to get it so when I started moving right or left the screen moved the opposite direction. but to be honest I don't think my tilemapping is gonna work. so could someone make me a tutorial on a sidescrolling tilemap? And I want this for a platformer jsyk

Thanks

BTW, what platformer are you making?

There are plenty of tutorials lying around this site if you can use that search box up there

It's a bit difficult for platformers, especially if you want it to run fast, but you'll figure it out ^^

EDIT: I'll start writing a scrolling platformer tutorial if you guys want.

[saintrunner]

Yeah I did search it but I couldn't find something that made sense, so yeah thanks I'd really appreciate it leafy

[turiqwalrus]

check the tutorials section...
at the very bottom, you should be able to see yunhua's tutorial...
it's slightly unoptimized for tutorial purposes, but it should be fine.

[saintrunner]

Yeah I saw that but I didn't understand it much. Plus thats for an RPG and I want one easily fitted for a platformer, I'll check it out again anyways thanks, I might understand it now since the last time I checked it was a month ago before I actually understood tile mapping

If your platformer is smooth scrolling with physics, you might have to change the code up quite a bit.  If it uses simple physics, then you can use the same code pretty much, except have a constant gravity.

[saintrunner]

this is my code...can you help modify it to work? and I know the map is small I'll make it larger once i get the scrolling

could you tell me what each of your pointers, not counting the sprite pointers, do?  I'm really bad at understanding other people's code. 

[saintrunner]

A is columns and B is rows, J is for jumping, X and Y are for your characters position, and D is just the direction you face

[yunhua98]

In line 50, why do you have pxl-test(X, Y+8) twice?  as for scrolling, I'm working on that right now.

Just a copy and paste error sorry, and THANKS SO MUCH FOR HELPING ME!!!

On TI-Planet ( here ), a member suggested this :

Si tu veux faire du tilemapping pixel par pixel, il faut en effet utiliser le smooth scrolling. Je vais essayer de t'expliquer comment faire :
Tout d'abord , tu dois changer de signe deux variables (I et J) en fonction de la direction où tu vas comme ceci :
CODE: TOUT SÉLECTIONNER
:If getKey(3) and (I=0) and (J=0)
:1→I
:End
:If getKey(2) and (I=0) and (J=0)
:-1→I
:End
:If getKey(1) and (I=0) and (J=0)
:1→J
:End
:If getKey(4) and (I=0) and (J=0)
:-1→J
:End


Ensuite tu les ajoutes à H et V (le décalage horizontale et verticale sur la map entre 0 et 8 ) :
CODE: TOUT SÉLECTIONNER
H+I+I→H
V+J+J→V

Lorsque tu as bougé de 8 pixels, tu rajoute (ou soustrait 1) à la position horizontale/verticale (ici P = horizontale et Q = verticale) :
CODE: TOUT SÉLECTIONNER
:If H-8=0 or (H+8=0
+I→P
:0→H→I
:End
:If V-8=0 or (V+8=0
:Q+J→Q
:0→V→J
:End


En tout, tu as :
CODE: TOUT SÉLECTIONNER
:Repeat getKey(15)
:
:If getKey(3) and (I=0) and (J=0)
:1→I
:End
:If getKey(2) and (I=0) and (J=0)
:-1→I
:End
:If getKey(1) and (I=0) and (J=0)
:1→J
:End
:If getKey(4) and (I=0) and (J=0)
:-1→J
:End
:
:
:H+I+I→H
:V+J+J→V
:
:If H-8=0 or (H+8=0
+I→P
:0→H→I
:End
:If V-8=0 or (V+8=0
:Q+J→Q
:0→V→J
:End
:
:sub(MAP)
:Pt-Off(48,32,Pic1
:DispGraphClrDraw
:End
:Return


sub(MAP) appellera la fonction qui s'occupe d'afficher la map à l'écran et Pic1 contient le sprite du personnage.

Pour voir les tiles sur le bord quand tu te déplace, tu dois avoir préalablement affiché la colonne/ligne d'après/avant.
Voilà maintenant le code de la fonction MAP :
CODE: TOUT SÉLECTIONNER
:Lbl MAP
:For(Y,0,9
:For(X,0,13
:Pt-On(X*8-8-H,Y*8-8-V,{Y+Q*[largeur de la map]+X+P+GDB1}*8+Pic0
:End
:End
:Return

avec GDB1, un pointeur sur la map et Pic0, un pointeur sur les tiles.

En espérant t'avoir aidé.
