New page

__NOTOC__
This function attempts to read the specified amount of bytes from the file. The actual amount of bytes read equals to the length of the Lua string.

==Syntax==
<syntaxhighlight lang="lua">
string file.read ( int readCount )
</syntaxhighlight>

==Arguments==
*'''readCount:''' the amount of bytes to read from the file

==Returns==
This function returns a string that contains the bytes that have been read from the file.

==Example==
<section name="Client" class="client" show="true">
This snippet returns whether the file that is passed to it looks like a collision file.
<syntaxhighlight lang="lua">
local function isCollisionFile( file )
-- Check whether the file is big enough to be a collision file.
if ( ( file.size() - file.tell() ) <= 8 ) then
return false;
end

-- Read the header checksum from the file.
local checksum = file.read( 4 );

-- Check whether the checksum is correct.
return ( checksum == "COLL" ) or ( checksum == "COL2" ) or ( checksum == "COL3" ) or ( checksum == "COL4" );
end

-- Verify a collision file.
local myColFile = fileOpen( "collisions/fence.col" );
local result = false;

if ( myColFile ) then
result = isCollisionFile( myColFile );

myColFile.destroy();
end

outputChatBox( "proper collision of fence model: " .. result );
