    <desc>Determines the material type at the specified position in the landscape. Returns a material index which can be used for comparison e.g. with <funclink>Material</funclink>. For sky areas the function returns -1.</desc>
    <remark>This functions only processes static materials - moving material pixels such as rain or snow are not evaluated.</remark>

        <text>Part of a clonk script: if 200 pixels below the calling object oil is found a message is displayed.</text>
