Hey, can you post the error message, too?

And there's already some Pokemon-like game planned (Buinomon).
Maybe you can use the information from the Buinomon-Threads instead of doing everything yourself: viewtopic.php?f=10&t=550&hilit=buinomon

Of course I don't want to discourage you from your own project, I just wanted to show you that there's already something in that direction.

Hello GlueMen,

nice to see more RPG games

being new to Gamebuino myself, I ran into similar troubles when first attempting to make my characters look in different directions and cycle through the animation.

First of all, the first of your sprite data is just 15 characters long, not 16 as defined.
Second, a byte can only be 8 bit long.

Example:

Code: Select all

const byte Bild1[] PROGMEM = {16,16,
B00000000,B00000000,
B00000000,B00000000,
B00000100,B01000000,
B00000100,B01000000,
B00000100,B01000000,
B00000000,B00000000,
B00000000,B00000000,
B00000000,B00000000,
B00000000,B00000000,
B00000000,B00000000,
B00010000,B00110000,
B00011000,B01100000,
B00001111,B10000000,
B00000000,B00000000,
B00000000,B00000000,
B00000000,B00000000,
};

thank you guys it helped me verymuch^^
but i got an other question now:P
how can i script is that the character is looking in the direktion im walking to and after it its looking that way also right now i got this but its not what i want

Code: Select all

  if(gb.buttons.pressed(BTN_C)){
    gb.titleScreen(F("PokeMon"));
  } 
  if(gb.buttons.repeat(BTN_LEFT,1)){
    trainer_x = trainer_x - trainer_vx;
    gb.display.drawBitmap(trainer_x,trainer_y,trainerleft);
    }
  if(gb.buttons.repeat(BTN_RIGHT,1)){
    trainer_x = trainer_x + trainer_vx;
    gb.display.drawBitmap(trainer_x,trainer_y,trainerright);
    }
  if(gb.buttons.repeat(BTN_UP,1)){
    trainer_y = trainer_y - trainer_vy;
    gb.display.drawBitmap(trainer_x,trainer_y,trainerup);
    }
  if(gb.buttons.repeat(BTN_DOWN,1)){
    trainer_y = trainer_y + trainer_vy;
    gb.display.drawBitmap(trainer_x,trainer_y,trainerdown);
    }


right now the char is just showing of if one or more buttons are pressed and if i press more than one buttons also more chars display

[Marcus]

You could either use "else if" or use a variable to memorize what direction was pressed first and disable further input until the key is released again.

[GlueMen]

have you got an example for me its very hard for me to do this without some little helps it dont need to be an working example for my script so you could give me a script what you are working on where it is working
so that i can see how it works i already tried with while but then broke the comlpete game and i also tried with if button ... botton... and button... are pushed dont show the basic

(i was trieng to do it that if i dont press a button the char is looking down and if i push a button its justone picture but then the pictures are overlayed ) im sooo bad at scripting right now
