Raining inside the houses

How do i prevent the rain to pass throught the models?
When it's raining and i enter the house, it's raining inside...

Thanks in advance

-make a trigger, that turns rain off, if youare in the house
-use ent_move with a raindrop and destroy if it collides
-use c_content to check if the position of the raindrop is in a solid block (but hee is the disadvantage, that they can fall "trough" the wall if they are too fast)

The middle one seems to be what i want, can you be more specific about how to implement such a code?
Thanks

you create randomly single rainsdrops over the players position (must be entites/sprites)
and just move them down with a c_move:
Code:

---

c_move(me,nullvector,vector(0,0,-10),IGNORE_PASSABLE)

---

and after that move you can check the trace_hit varialbe if something was hit => move the entity up again.

Yikes, though -- c_move with raindrops will be SLOOOOWWW...

Using c_trace might be faster, and you can use it with particles too. Trace from the current position to the next position, and if it hits something, destroy it:
Code:

---

var endpos[3]; // VECTOR endpos in Lite-C
vec_set(endpos, my.x);
vec_add(endpos, my.vel_x);
c_trace(my.x, endpos, IGNORE_PASSABLE || IGNORE_PASSENTS);
if(trace_hit) {my.lifespan = 0;}

---

I don't use lite-c
Do i place it in the raining function?

You'd put it in the action or particle function for your raindrops. If you're using entities instead of particles, use ent_remove(me) instead of my.lifespan = 0.

you could do a trace instruction upwards to look for a roof every so often
and create a global var ...say var im_inside=0; and if trace hits a roof
above you can change im_inside=1; , in the while loop that controls your rain
put an if statement like so

while(1)
{
if(im_inside==0)
{
rain
}
else
{wait(1);
}
wait(1);
}

know what i mean?

c_move is slow if you use GLIDE...else its not that slow-if you compare it with c_trace. So don't Yike around

Thanks alot for all you're help

If your geometry is relatively simple, then you can precalculate the drops falltime first, so you won't need to do traces or movement on each drop.

Ask Sp|ke, I don't have the code anymore, but he might...

Here is a code i made for you!

Code:

---

bmap the_rain = "rain.pcx";

function remove_me();
function fall();
function raindrops();



function main
{
	level_load("YOURMAP.wmb"); // load your map
	wait(3);
	raindrops(); // start the weather effect
}

function raindrops()
{
	while(1)
	{
		vec_set(temp, vector(random(1000)-500,random(1000)-500,300)); // Choose your size its in a random area between 1000 and -500 quants. it starts on a high of 300 quants
		ent_create("rain.pcx", temp, fall); // create the raindrops
		sleep(0.2); // Choose your own speed, you can also use wait
	}
	
}

function fall()
{
	my.enable_entity = on; // sensitive for entitys (player)
	my.enable_block = on; // sensitive for blocks (level)
	my.event = remove_me; // The event who starts when he hit a entity or a block
	while(my != 0) // while i´m not removed
	{
		c_move(my, vector(0,0,-8*time_step), nullvector, 0); //c_move without "glide" you can change the numbers in vector if you want ti drop it more fast and maybe a bit angular
		wait(1);		
	}
}

function remove_me() // the event
{
	if(EVENT_TYPE == EVENT_block) // if raindrops hit a wall or a buildung or whatever
	{
		wait(3); // you can take a higher value if you want your raindrops life longer. better do that if you need snow
		ent_remove(my); // remove raindrop
	}
	if(EVENT_TYPE == EVENT_entity)
	{
		wait(3);
		ent_remove(my);
	}
}

You can change your weathereffect if you use variables. For example you can create a variable with the name "rain_amount = 0.2" you can use that in the sleep(rain_amount) in the raindrops function. In another script you can simply change this value and enforce the rainfall or damp it.

Greetings and have fun!
