does anybody know the way to convert this code

sky bla
{
speed_u = 10;
}

to Lite-C code?

my way

ENTITY* bla =
{
flags2 = SKY;
}

void sky_speed_startup()
{
while(1)
{
bla.u+=10*time_step;
wait(1);
}
}

is there a more convenient way to do that? uv shifting is too fast for a sky, and lower values(below 0.001) don't move it at all

Problem solved
speed_u/v should be replaced by u/v in sky definition

while you are on the subject of u/v , ive tried to use u/v on a water looking sprite to simulate the current and get errors , is this no longer available?
