Very simple mistake that made me loose my sleep and now I am too lazy to finish my Ludum Dare entry (I haven't even started as planned and not sure if I want to go for the Jam)

Code: if (hasHitWall(r)); { // do stuff }

Optimus: That´s why i zoom the Text-Editor a lot when coding...lets me see such typos directly. If your Editor doesn´t support zooming just use a bigger font! ;)
any decent compiler should warn you about such constructs...

Maybe I didn't see the warning.

Generally a problem amongst coders! Most just never look at warnings at all...while they should be handled like Errors in many cases.
It´s really a bad habit every coder that wants to be a good coder should get rid of asap!
Warning as errors is the way to go!

Rudi, did you miss a struct for low and high?

Code: union Flags { WORD EFLAGS; BYTE low; BYTE high; struct flagbits bits; };

Code: str[strlen(str)] = 0;

In a commercial project with millions of users.

0xF: seems like a smart hack to ensure the string always ends with a 0, which is actually useful to avoid buffer memory leaks and such C foley. not sure if there are any misuse consequences though?!

although strings should end with \0 not 0 itself... hmm.. fuck me if i'll ever know any proper c trickery.

//code of random line
DrawLine(Random2D(), Random2D());

//TODO: add Threading
psenough: strlen counts the characters up to the first \0 (which is equal to 0)... i.e. this is just a (very expensive) NOP
Perhaps it's a fix for a race condition in case another thread overwrites the 0 with garbage inbetween the strlen() and the write. :P

More likely written by someone who switches between programming languages a lot.

If the string hasnt a 0 it will write a 0 somewhere else in memory.
If the string already has 0 it an expensive shitload of nop.
Thats clearly retarted.

It just zeroes twice to make the string extra secure!

When writing a math lib at night, always working with transposed matrices, and don't get the matrix inverse correct.

Code: // Shit cheat, just reverse the transformations. Matrix Matrix::Reverse() const { Matrix matrix; // Inverse determinant of rotation part. float f = 1.0f / (M11 * (M22 * M33 - M32 * M23) - M21 * (M12 * M33 - M32 * M13) + M31 * (M12 * M23 - M22 * M13)); // Rotation. matrix.M11 = f * (M22 * M33 - M32 * M23); matrix.M12 = -f * (M12 * M33 - M32 * M13); matrix.M13 = f * (M12 * M23 - M22 * M13); matrix.M21 = -f * (M21 * M33 - M31 * M23); matrix.M22 = f * (M11 * M33 - M31 * M13); matrix.M23 = -f * (M11 * M23 - M21 * M13); matrix.M31 = f * (M21 * M32 - M31 * M22); matrix.M32 = -f * (M11 * M32 - M31 * M12); matrix.M33 = f * (M11 * M22 - M21 * M12); // Translation. matrix.M14 = -(M14 * matrix.M11 + M24 * matrix.M12 + M34 * matrix.M13); matrix.M24 = -(M14 * matrix.M21 + M24 * matrix.M22 + M34 * matrix.M23); matrix.M34 = -(M14 * matrix.M31 + M24 * matrix.M32 + M34 * matrix.M33); // Last row. matrix.M41 = 0.0f; matrix.M42 = 0.0f; matrix.M43 = 0.0f; matrix.M44 = 1.0f; return matrix; }
