Problem with "seminvisible" wall

[Nahuel]

I have tried to create a function in that a brush is invisible and when it is activated be visible and then be invisible again (in this case it disappears).
For this I have used the resource of "alpha".
The function works well being visible but the "self.wait" sometimes fails. The time so that the brush disappears changes too much, the self wait is never precise!
And I do not know why this happens!!!!!!!!!!!!
does an alternative occur to you for a similar function?

Code: Select all

void() removesemiwall =
{
self.model = string_null;
   self.solid = SOLID_NOT;
   self.movetype = MOVETYPE_NONE;
};
void() semiwall =
{
               self.alpha = self.count;

self.nextthink = time + self.wait ;
self.think = removesemiwall;
};
void() func_semiwall =
{   
if (!self.count)
self.count = 1;
if (!self.wait)
self.wait = 0.1;
self.angles = '0 0 0';
   self.movetype = MOVETYPE_PUSH;
   self.solid = SOLID_BSP;
   setmodel (self, self.model);
self.use = semiwall;
 self.alpha = -1;
};


Thanks in advance!!!!!!!!!!

i vaguely remember that self.think is unreliable on SOLID_BSP entities. If that's true it could your problem.

instead of using .think use .blocked as the function.

self.think is fully reliable on solid_bsp objects...
except on movetype_push objects, it works slightly differently, using self.ltime instead of time.

void() semiwall =
{
self.alpha = self.count;
self.nextthink = self.ltime + self.wait;
self.think = removesemiwall;
};

as a general rule of thumb, you should avoid using alpha < 1/255.0 as engines might consider that to be fully visible.

thank you Spike!
Now the function works very fine!!!!!
