I have these two errors: --------------------Configuration: 3dMaze5 - Win32 Debug-------------------- Compiling... Main.cpp C:\3dMaze5\Main.cpp(95) : warning C4018: ''<'' : signed/unsigned mismatch C:\3dMaze5\Main.cpp(211) : error C2446: ''<'' : no conversion from ''double *'' to ''double'' There is no context in which this conversion is possible C:\3dMaze5\Main.cpp(211) : error C2115: ''<'' : incompatible types Error executing cl.exe. 3dMaze5.exe - 2 error(s), 1 warning(s) ---------------------------------------------------------------- These are my declarations: double MaxX; double MaxY; double MinX; double MinY; double MaxX2[1]; double MaxY2[1]; double MinX2[1]; double MinY2[1]; These are how they are used: MaxY = posx + 1; MinX = posx - 1; MaxY = posz + 1; MinY = posz - 1; MaxX2[0] = 22.5;MaxY2[0] = 16;MaxX2[0] = 22.5;MinY2[0] = 16.5; MaxX2[1] = 22.5;MaxY2[1] = 16;MaxX2[1] = 22.5;MinY2[1] = 16.5; for(Num = 0;Num == 1; Num = Num + 1){ if(MaxY > MinY2[Num] && MinY < MaxY2[Num] && MaxX > MinX2[Num] && MinX < MaxX2){ Collision = true; } }

At the end of the condition you''ve forgotten to bracket the array: MinX < MaxX2 - looks like it should be MinX < MaxX2[num]

quote:Original post by Drakon
for(Num = 0;Num == 1; Num = Num + 1){
// whatever was here...
}

Don't forget the errors it doesn't tell you about... The body of the for loop will never be executed. Try Num <= 1 instead of Num == 1.

[edit 1]:

// Here is how it _should_ be... (assuming your logic is correct)double MaxX2[2]; // note it isn't [1] anymoredouble MaxY2[2];double MinX2[2];double MinY2[2];These are how they are used:for(Num = 0;Num <= 1; Num = Num + 1) // Num <= 1 not Num == 1{  if(MaxY > MinY2[Num] && MinY < MaxY2[Num] && MaxX > MinX2[Num] && MinX < MaxX2[Num]) // note MaxX2 now is MaxX2[Num]  {     Collision = true;  }}
