# Resetting the state of a 2D vector
|
|
|
|
[Русская версия / Russian version](reset-rus.md)
|
|
|
|
These functions set all coordinates of 2D vectors to 0.
|
|
|
|
Function for **BGC_FP32_Vector2**:
|
|
|
|
```c
|
|
inline void bgc_fp32_vector2_reset(BGC_FP32_Vector2* const vector);
|
|
```
|
|
|
|
Function for **BGC_FP64_Vector2**:
|
|
|
|
```c
|
|
inline void bgc_fp64_vector2_reset(BGC_FP64_Vector2* const vector);
|
|
```
|
|
|
|
Each of these functions is equivalent to the following lines of code:
|
|
|
|
```c
|
|
vector->x = 0;
|
|
vector->y = 0;
|
|
```
|
|
|
|
You should pass valid pointers to these functions. The NULL (0) value is also
|
|
considered invalid.
|
|
|
|
This function is good for setting up the initial state of a 2D vector.
|
|
|
|
Example of use:
|
|
|
|
```c
|
|
#include <stdio.h>
|
|
#include <basic-geometry.h>
|
|
|
|
int main()
|
|
{
|
|
BGC_FP32_Vector2 v;
|
|
|
|
bgc_fp32_vector2_reset(&v);
|
|
|
|
printf("x = %f, y = %f\n", v.x, v.y);
|
|
|
|
return 0;
|
|
}
|
|
```
