NAME¶

SDL_RectsEqualEpsilon - Determine whether two floating point rectangles are equal, within some given epsilon.

SYNOPSIS¶

#include <SDL3/SDL_rect.h>

SDL_FORCE_INLINE bool SDL_RectsEqualEpsilon(const SDL_FRect *a, const SDL_FRect *b, float epsilon);

DESCRIPTION¶

Rectangles are considered equal if both are not NULL and each of their x, y, width and height are within epsilon of each other. If you don't know what value to use for epsilon, you should call the SDL_RectsEqualFloat function instead.

Note that this is a forced-inline function in a header, and not a public API function available in the SDL library (which is to say, the code is embedded in the calling program and the linker and dynamic loader will not be able to find this function inside SDL itself).

FUNCTION PARAMETERS¶

a

the first rectangle to test.

b

the second rectangle to test.

epsilon

the epsilon value for comparison.

RETURN VALUE¶

Returns true if the rectangles are equal, false otherwise.

THREAD SAFETY¶

It is safe to call this function from any thread.

AVAILABILITY¶

This function is available since SDL 3.2.0.
