I have problems with difference betwen old and new engine version. In some situation with 8.30.3 rel_for_screen and vec_to_screen not work, and i thinking it's maybe a bug?
I made example where rel_for_screen work good in some previous version (tested in 8.03.2) but not in new beta:
ENTITY panel_ent {
type = "test_panel.mdl";
VIEW = camera;
flags = visible;
layer = 14;
pan = 35; tilt = 15; roll = -10;
}
var panel_distance[2] = 200,200;
var panel_distance_y[2] = 0,0;
function handle_panels_startup {
while (1) {
temp.x = 20 * screen_size.x/800;
temp.y = (20 + panel_distance_y[1]) * screen_size.y/600;
temp.z = panel_distance[1];
rel_for_screen(temp.x,camera);
vec_set(panel_ent.x,temp.x);
wait(1);
}
}
Now i have almost good results when i change rel_for_screen to vec_for_screen.
There also problem with vec_to_screen. I have different result in last beta. Here example where i check did entity is visible on screen, but this now not work like before:
vec_set(temp.x,vector(my.x,my.y,my.z + 5));
vec_to_screen(temp.x,camera);
if (temp.x < screen_size.x + 100 && temp.y < screen_size.y + 50 && vec_dist(my.x,vector(camera.x,0,camera.z)) < 1500){
I wonder why this happen?
