Foreword

I love the MapAndreas plugin, but I find so unfortunate that it uses ~70 MB's of RAM memory, so I started browsing the topic and found out that you can actually get the same results using fseek by setting the position indicator of the file using a small calculation instead of allocating the whole map into the memory.

Features

This include has exactly the same features as the MapAndreas plugin and is as accurate - there's simply no difference in terms of functioning between them:

	MapAndreas Plugin	MapAndreas Include
Memory usage	~70 MB RAM	Nothing*
Accuracy		EXACTLY the same accuracy as the plugin
Performance	The plugin is really fast (because the data is allocated in the memory first and has the C++ performance advantage)	This include is slower than the plugin (obviously because we're using fseek and read all time again plus we don't have the C++ performance advantage in this case)
Initialize time	Takes some time to allocate the memory (~5 seconds)	No waiting needed - immediately ready for use

* Although every script needs some memory (depending what you're using and how much) to execute. I assume this will use a couple of hundred kilobytes.

Function(s)

We have only one function:

pawn Код:

stock Float: GetPointZPos(const Float: fX, const Float: fY, &Float: fZ = 0.0);

It returns the result and stores it in fZ (if variable defined).

Example(s)

Here are some basic examples:

pawn Код:

printf("The Z-coordinate of X = 2033.55 | Y = 1007.73 is Z = %.02f", GetPointZPos(2033.55, 1007.73));

Or you can just do it this way:

pawn Код:

new
    Float: fZ
;
GetPointZPos(1254.65, -554.55, fZ);
printf("The Z-coordinate of X = 1254.65 | Y = -554.55 is Z = %.02f", fZ);

Results:

Код:

The Z-coordinate of X = 2033.55 | Y = 1007.73 is Z = 9.81
The Z-coordinate of X = 1254.65 | Y = -554.55 is Z = 67.48
