Hey!
For attaching videos, I would recommend (f.e.) using youtube. If you use platforms such as youtube, other users will be confident that content is safe (no viruses, etc).
As for sharing the code, you can simply use code tags:
[.code] // code here [./code] (don't forget to remove dots).
As for the error 'load_level is undeclared', maybe it's a typo in your message, but it's visaversa -> 'level_load (STRING* filename);'
Another thing to mention is, that if you don't include acknex header into your project, sometimes it won't recognize acknex function (#include <acknex.h> at the top).
Here is a small example:
#include <acknex.h> // include acknex header
void main()
{
fps_max = 60; // set fps limit
warn_level = 6; // show all errors
// initialize video device
video_mode = 7;
video_switch(video_mode, 0, 0);
// empty level
level_load("");
// loop untill 'esc' is pressed
while(!key_esc)
{
// draw 'hello world' at x = 10 y = 10 pixel position with white color
draw_text("hello world!", 10, 10, COLOR_WHITE);
// wait one frame, then repeat
wait(1);
}
// exit the game when we break from the loop
sys_exit(NULL);
}
Best regards!
