Slow down speedup char [SOLVED]

[Candle]

Is there anyway to let the user  speedup/slow down  the char in the game with some controls with code ?

[Ashen]

SetCharacterSpeed (CHARID, speed)
SetCharacterSpeedEx (CHARID, x_speed, y_speed)
or, in the newer versions
Character.SetWalkSpeed(int x_speed, int y_speed)

What exactly do you want to do?
If you want it to be changeable by the player, you'll also need the character[CHARID].walkspeed variable, e.g.:

Code: ags

//on keypress
if (keycode == 372) { // 'Up' arrow
  StopMoving (EGO); // Can't change speed while char is moving
  SetCharacterSpeed (EGO, character[EGO].walkspeed + 1);
}
if ((keycode == 380) && (character[EGO].walkspeed > 1)) { // 'Down' arrow. Won't go lower thatn 1, since negative values cause errors, and 0 will jump straight to the mouse.
  StopMoving (EGO);
  SetCharacterSpeed (EGO, character[EGO].walkspeed - 1);
}

Of course, it could be done with GUI buttons or a slider, or whatever.

Thanks for helping me . I use the last code you gave but it gave me the if error .

Code: ags

#sectionstart on_key_press  // DO NOT EDIT OR REMOVE THIS LINE
function on_key_press(int keycode) {
  // called when a key is pressed. keycode holds the key's ASCII code
  if (IsGamePaused() == 1) keycode=0;  // game paused, so don't react to keypresses
  if (keycode==17)  QuitGame(1);   // Ctrl-Q
  if (keycode==363 && GetCursorMode() != 7) Save();   // F5
  if (keycode==365) Load();  // F7
  if (keycode==367) RestartGame();  // F9
  if (keycode==434) SaveScreenShot("scrnshot.bmp");  // F12
  if (keycode==9 && GetCursorMode() != 7) show_inventory_window();  // Tab, show inventory

  if (keycode==19)  Debug(0,0);  // Ctrl-S, give all inventory
  if (keycode==22)  Debug(1,0);  // Ctrl-V, version
  if (keycode==1)   Debug(2,0);  // Ctrl-A, show walkable areas
  if (keycode==24)  Debug(3,0);  // Ctrl-X, teleport to room
}
if (keycode == 372) { // 'Up' arrow
  StopMoving (EGO); // Can't change speed while char is moving
  SetCharacterSpeed (EGO, character[EGO].walkspeed + 1);
}
if ((keycode == 380) && (character[EGO].walkspeed > 1)) { // 'Down' arrow. Won't go lower thatn 1, since negative values cause errors, and 0 will jump straight to the mouse.
  StopMoving (EGO);
  SetCharacterSpeed (EGO, character[EGO].walkspeed - 1);
}

I think you've got an extra brace after if (keycode == 24)..., putting the new code outside the on_key_press script:

Code: ags

#sectionstart on_key_pressÃ,  // DO NOT EDIT OR REMOVE THIS LINE
function on_key_press(int keycode) {
Ã,  // called when a key is pressed. keycode holds the key's ASCII code
Ã,  if (IsGamePaused() == 1) keycode=0;Ã,  // game paused, so don't react to keypresses
Ã,  if (keycode==17)Ã,  QuitGame(1);Ã,  Ã, // Ctrl-Q
Ã,  if (keycode==363 && GetCursorMode() != 7) Save();Ã,  Ã, // F5
Ã,  if (keycode==365) Load();Ã,  // F7
Ã,  if (keycode==367) RestartGame();Ã,  // F9
Ã,  if (keycode==434) SaveScreenShot("scrnshot.bmp");Ã,  // F12
Ã,  if (keycode==9 && GetCursorMode() != 7) show_inventory_window();Ã,  // Tab, show inventory

Ã,  if (keycode==19)Ã,  Debug(0,0);Ã,  // Ctrl-S, give all inventory
Ã,  if (keycode==22)Ã,  Debug(1,0);Ã,  // Ctrl-V, version
Ã,  if (keycode==1)Ã,  Ã, Debug(2,0);Ã,  // Ctrl-A, show walkable areas
Ã,  if (keycode==24)Ã,  Debug(3,0);Ã,  // Ctrl-X, teleport to room
} // <-- REMOVE THIS BRACE
if (keycode == 372) { // 'Up' arrow
Ã,  StopMoving (EGO); // Can't change speed while char is moving
Ã,  SetCharacterSpeed (EGO, character[EGO].walkspeed + 1);
}
if ((keycode == 380) && (character[EGO].walkspeed > 1)) { // 'Down' arrow. Won't go lower thatn 1, since negative values cause errors, and 0 will jump straight to the mouse.
Ã,  StopMoving (EGO);
Ã,  SetCharacterSpeed (EGO, character[EGO].walkspeed - 1);
}

Removed that and got this error ?

OK, so //<-- REMOVE THIS BRACE should be //<-- THIS BRACE SHOULD BE AT THE VERY BOTTOM

Add an '}' at the end of the script,:

Code: ags

    SetCharacterSpeed (EGO, character[EGO].walkspeed - 1);
  }
} //<-- HERE

Then check it with the match brace function (Ctrl-B), just to be safe.

This is the code I have now .

Code: ags

function on_key_press(int keycode) {
  // called when a key is pressed. keycode holds the key's ASCII code
  if (IsGamePaused() == 1) keycode=0;  // game paused, so don't react to keypresses
  if (keycode==17)  QuitGame(1);   // Ctrl-Q
  if (keycode==363 && GetCursorMode() != 7) Save();   // F5
  if (keycode==365) Load();  // F7
  if (keycode==367) RestartGame();  // F9
  if (keycode==434) SaveScreenShot("scrnshot.bmp");  // F12
  if (keycode==9 && GetCursorMode() != 7) show_inventory_window();  // Tab, show inventory

  if (keycode==19)  Debug(0,0);  // Ctrl-S, give all inventory
  if (keycode==22)  Debug(1,0);  // Ctrl-V, version
  if (keycode==1)   Debug(2,0);  // Ctrl-A, show walkable areas
  if (keycode==24)  Debug(3,0);  // Ctrl-X, teleport to room
}

if (keycode == 372) { // 'Up' arrow
  StopMoving (MIKE); // Can't change speed while char is moving
  SetCharacterSpeed (MIKE, character[MIKE].walkspeed + 1);
}
if ((keycode == 380) && (character[MIKE].walkspeed > 1)) { // 'Down' arrow. Won't go lower thatn 1, since negative values cause errors, and 0 will jump straight to the mouse.
  StopMoving (MIKE);
  SetCharacterSpeed (MIKE, character[MIKE].walkspeed - 1);
}
}

The first brace, the one after if (keycode==24)..., is back in there, AS WELL as the final one. Code should be:

Code: ags

function on_key_press(int keycode) { // Start of on_key_press
  // called when a key is pressed. keycode holds the key's ASCII code
  if (IsGamePaused() == 1) keycode=0;  // game paused, so don't react to keypresses
  if (keycode==17)  QuitGame(1);   // Ctrl-Q
  if (keycode==363 && GetCursorMode() != 7) Save();   // F5
  if (keycode==365) Load();  // F7
  if (keycode==367) RestartGame();  // F9
  if (keycode==434) SaveScreenShot("scrnshot.bmp");  // F12
  if (keycode==9 && GetCursorMode() != 7) show_inventory_window();  // Tab, show inventory

  if (keycode==19)  Debug(0,0);  // Ctrl-S, give all inventory
  if (keycode==22)  Debug(1,0);  // Ctrl-V, version
  if (keycode==1)   Debug(2,0);  // Ctrl-A, show walkable areas
  if (keycode==24)  Debug(3,0);  // Ctrl-X, teleport to room
  if (keycode == 372) { // Start of 'Up' arrow code
    StopMoving (MIKE); // Can't change speed while char is moving
    SetCharacterSpeed (MIKE, character[MIKE].walkspeed + 1);
  }// End of 'Up' arrow code
  if ((keycode == 380) && (character[MIKE].walkspeed > 1)) { //Start of 'Down' arrow code. 
    StopMoving (MIKE);
    SetCharacterSpeed (MIKE, character[MIKE].walkspeed - 1);
  } // End of 'Down' arrow code
} //End of on_key_press

Sorry didn't see that Ashen ,, thanks for all the help .. your the man when it comes to this code ..

Candle: You've given me the idea of "translating" these error messages. Sometimes the messages that the AGS Editor gives are not always apparent and might even be a bit cryptic. At least in the future you will always be able to reference it.
