2D array example (1 Race engine)

//2D Array Example (1 Race engine) made by BigETI©
//
//Lets start with enum to define the positions of the datas and also to get the informations easier from the 2D array.

//Defines
#define RACE_CHECKPOINT_SIZE    10.0

//Enums
enum RaceCPInfos //<-- Returns the max amount of variables below. (In this case: 4)
{
    Race_STATE_CP, //<-- returns 0
    Float:Race_X_CP, //<-- returns 1
    Float:Race_Y_CP, //<-- returns 2
    Float:Race_Z_CP, //<-- returns 3
}

//News
new countracepos = 0;

new RaceCPInfo[][RaceCPInfos] = { //<-- We create now a 2D array variable
{0, 0.0, 0.0, 0.0}, //<-- CP 1 info..
{0, 0.0, 0.0, 0.0}, //<-- CP 2 info..
{0, 0.0, 0.0, 0.0}, //<-- CP 3 info..
{0, 0.0, 0.0, 0.0}, //<-- CP 4 info..
//... And so on...
{1, 0.0, 0.0, 0.0} //<-- Last CP info. (Warning: After the '}' at the last 1D array field you shouldn't add a comma there since the comma shows for the script that you want to add more 1D arrays but in this case you won't.)
