Getting tire damage states - MP2 - 11.07.2012

Hi. I'm not good with binary and stuff. I need to know whether both the back tires are popped on a vehicle, from GetVehicleDamageStatus.

To pop the back two tires, I do this:

pawn Код:
UpdateVehicleDamageStatus(GetPlayerVehicleID(playerid), Panels, Doors, Lights, 1 | (0 << 1) | (1 << 2) | (0 << 3));
But I didn't write that, so I don't understand how to 'reverse' it for GETTING the states.

I use this. I don't know who originally wrote this, but I don't take credit for it;

pawn Код:
encode_tires(tires1, tires2, tires3, tires4) {
    return tires1 | (tires2 << 1) | (tires3 << 2) | (tires4 << 3);
}

That converts 4 tire states in to the binary number, I need the opposite.

Maybe...
pawn Код:
new panels,doors,lights,tires;
GetVehicleDamageStatus(vehicleid, panels, doors, lights, tires);
if(tires == 0101)
return SendClientMessage(playerid, 0xFF0000AA, "Your back tires are popped brah.");
just my guess.

Re: Getting tire damage states - MP2 - 11.07.2012

No, not JUST the back ones.

I have a feeling it will be something like

if(tires & 1 && tires & 3) // Back tires are popped

EDIT: Just tested, that doesn't work :/

Ah okay, this is simple. I've done it. Well not with tyres but with panels.

wait are you sure that code pops back and not front tyres? from logic it seems 1010 would pop back front and 0101 would pop back tyres

pawn Код:
new panels, doors, lights, tires;
GetVehicleDamageStatus(vehicleid, panels, doors, lights, tires);
if(tires & 0101)//or in this weird case.. if(tires & 1010)
{
//back tyres are poped
}
//or it might be done by index which it seems like on the wiki
if(tires == 5) //or in this weird case.. if(tires == 10)
{
//back tyres are poped
}
also note you can't do tires & 3 with a bitwise operator, 3 is no a bit

I'm sorry for not using American English for tyres / tires.

Read https://sampwiki.blast.hk/wiki/TireStates

According to this, 0101 is popped back tires.

Re: Getting tire damage states - MP2 - 11.07.2012

Well I did this to test:

pawn Код:
if(Tires & 1000) SendClientMessage(playerid, -1, "Tire 0 popped.");
if(Tires & 0100) SendClientMessage(playerid, -1, "Tire 1 popped.");
if(Tires & 0010) SendClientMessage(playerid, -1, "Tire 2 popped.");
if(Tires & 0001) SendClientMessage(playerid, -1, "Tire 3 popped.");
But when I pop tire 0 it says I popped 0 AND 2.

EDIT: Ah, managed to fix it with 0b prefix:

pawn Код:
if(Tires & 0b1000) SendClientMessage(playerid, -1, "FL tire popped.");
if(Tires & 0b0100) SendClientMessage(playerid, -1, "BL tire popped.");
if(Tires & 0b0010) SendClientMessage(playerid, -1, "FR tire popped.");
if(Tires & 0b0001) SendClientMessage(playerid, -1, "BR tire popped.");
Thank you, Kar <3

Binary values need to be prefixed with 0b (like 0x for hex) otherwise the compiler will just read it as decimal.
Edit: Meh, too late.

Re: Getting tire damage states - MP2 - 11.07.2012

So, to check if both back tires are blown, should I do

pawn Код:
if(Tires & 0b0100 && Tires & 0b0001)
or
pawn Код:
if(Tires & 0b0101)
