Check this out:

Make sure to change RenderOperation to be OT_POINT_LIST...

where did I go wrong!!??

// read coordinates
FILE *fisierX;
FILE *fisierY;

fisierX = fopen("valoriX.txt","rt");//placed in \OgreSDK\bin\debug\
fisierY = fopen("valoriY.txt","rt");

k=0;//integer

ManualObject* manual = mSceneMgr->createManualObject("manual");
manual->begin("BaseWhiteNoLighting", RenderOperation::OT_LINE_STRIP);

while ( k<100 )
{
fscanf(fisierX,"%i",&xCitit); //integer
fscanf(fisierY,"%i",&yCitit); //integer
manual->position(xCitit, yCitit, 0.0);
k++;
}

manual->end();
mSceneMgr->getRootSceneNode()->createChildSceneNode()->attachObject(manual);

fclose(fisierX);
fclose(fisierY);

it says trere's an error with fscanf
pls help
