S3D_SET_CALLBACK

NAME

s3d_set_callback - sets a callback

SYNOPSIS

#include <s3d.h>

void s3d_set_callback(uint8_t event, s3d_cb func);

DESCRIPTION

Sets a callback for a certain event. this is very useful for event-oriented applications. event callbacks will not interrupt each other or the mainloop.

Warning

Defining callbacks will only work after calling s3d_init()

#include <inttypes.h>

void obj_click(struct s3d_evt event)
{
printf("object id %"PRIu32" got clicked", *((uint32_t *)event->buf));
}
...
s3d_set_callback(S3D_EVENT_NEW_OBJECT, obj_click);
// this will tell you when a object got clicked
