Confirmation Dialog
IntroductionI haven't posted a work of mine in this section for quite a while. A couple months ago, when I was putting confirmation dialogs across the game mode, I didn't want to do them all manually but instead I made a dynamic system for easy implementation. Simply said, you're able to state your question and pass necessary information in a single line with easy call-back processing later on. This script is a little advanced (while its usage is fairly basic) so if you don't understand parts of it feel free to ask! Here's an example usage that should speak for itself:
Syntax: ConfirmDialog(playerid, caption[], info[], callback[], ...);
Example: ConfirmDialog(playerid, "Confirmation", "Are you sure you want to purchase a Deagle for $5000?", "OnPlayerPurchaseWeapon", WEAPON_DEAGLE, AMMO, PRICE);
Example Processing:
Код:
public OnPlayerPurchaseWeapon(playerid, response, weaponid, ammo, price){
if(response){
GivePlayerMoney(playerid, -price);
GivePlayerWeapon(playerid, weaponid, ammo);
SendClientMessage(playerid, -1, "You bought a gun!");
}else{
SendClientMessage(playerid, -1, "You cancelled the purchase!");
}
}
Dependencies
- sscanf
- DIALOG_CONFIRM_SYS dialog ID defined
- OnDialogResponse ->
Код:if(dialogid == DIALOG_CONFIRM_SYS){ ConfirmDialog_Response(playerid, response); return 1; }

Confirmation dialogs:
"Are you sure?" made simple, without unnecessary additional dialog ID's
How does this work:
Syntax: ConfirmDialog(playerid, caption[], info[], callback[], ...);
Example:
ConfirmDialog(playerid, "Confirmation", "Are you sure you want to purchase a Deagle for $5000?",
"OnPlayerPurchaseWeapon", WEAPON_DEAGLE, AMMO, PRICE);
Example explanation:
playerid - playerid that needs something confirmed
"Confirmation" - Title / caption of the dialog window
"Are you su..." - Content / info / text of the dialog window
"OnPlayerPu..." - Callback that is called after answering the dialog
WEAPON_DEAGLE - Additional argument to be passed
AMMO - Additional argument to be passed
PRICE - Additional argument to be passed
^ The above will call the callback specified when answered. The callback has
two default arguments, "playerid" and "response". Then, the rest of your
additional arguments follow. Example callback for the ConfirmDialog used
in example:
public OnPlayerPurchaseWeapon(playerid, response, weaponid, ammo, price){
if(response){
GivePlayerMoney(playerid, -price);
GivePlayerWeapon(playerid, weaponid, ammo);
SendClientMessage(playerid, -1, "You bought a gun!");
}else{
SendClientMessage(playerid, -1, "You cancelled the purchase!");
}
}
[ ! ] NOTE: Right now, the additional arguments only work for integer values
