I'm not normally this nice, but because it's a personal thing...
PHP код:
#define MAX_ROADBLOCKS 20 // MAX_ROADBLOCKS will be set to 20 by default. This means that a player can only place up to 20 roadblocks at a time.
enum PlayerBlocks
{
pRoadblock[MAX_ROADBLOCKS], // Creates an array that will hold the object IDs for 20 roadblocks. This number depends on your MAX_ROADBLOCKS.
}
new Player[MAX_PLAYERS][PlayerBlocks];
CMD:roadblock(playerid, params[]) { // Command /roadblock
new free_rb_id = 0; // Set the initial object ID to '0'. Object IDs start at 1, so 0 is considered an invalid object ID.
for(new i = 0; i < MAX_ROADBLOCKS; i++) { // Start looping through all 20 roadblocks that could potentially be placed by the player.
if(!Player[playerid][pRoadblock][i]) { // If the roadblock is '0', a.k.a. does not exist, then we have an available slot.
free_rb_id = i; // Store the slot/index as our 'free roadblock ID'.
break; // Break the loop to stop it from continuing, because we have already found a valid slot.
}
}
if(!free_rb_id) return SendClientMessage(playerid, -1, "You cannot place any more roadblocks. Please remove one first.");
// If 'free_rb_id' is still 0, it means that the value was never changed in the loop. This means that every roadblock slot was being used.
new Float:Pos[4];
GetPlayerPos(playerid, Pos[0], Pos[1], Pos[2]);
GetPlayerFacingAngle(playerid, Pos[3]);
Pos[0] += (3 * floatsin(-Pos[3], degrees));
Pos[1] += (3 * floatcos(-Pos[3], degrees));

// Store the created object's ID into the available slot.
return 1;
}
CMD:removeall(playerid, params[]) { // Command /removeall
new Float:obx, Float:oby, Float:obz; // Create floats to store the roadblock's position.

return 1;
}
Note, when comparing floats, you can also use the function
Floatcmp.
