Client

This snippet returns whether the file that is passed to it looks like a collision file.

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 );
