Hello again

and how is it done if possible ??

i want to achieve a kind of masking effect.  if its inside its active, if its outside its inactive ...

thanks for answering, but thats the solution for actors. Is it possible to check if a normal entity or sprite is in a region ??
maybe i can do it by creating 50 actors, but thats not exactly what i want to do ...

i want to have little dustballs floating around in moonlight thats shining through a window. and they become invisible if they leave the moonbeam ...
just for some atmosphere ...

how can it be achieved.

i cannot make a png with a hole and let them fly behind it because of some other scene layers....

It will work for entities too. As you can see, the base of that code is the Scene.GetRegionAt() method, which returns a region at certain scene coordinates. It's up to you where you obtain the coordinates and it doesn't matter it they come from actor's position or from an entity or from anywhere else.

okay i see and i tried it but i cant get to work it properly.

i have to scripts.
the first the emitter ...

Code: [Select]

#include "scripts\base.inc"

var ANZAHL = 30;
var staubEntities = new Array(ANZAHL);
for (var i=1; i<20;i=i+1)
{
staubEntities[i] = Scene.CreateEntity();
var temp = staubEntities[i];
temp.X=Random(600,1280);
temp.Y=Random(450,1000);
temp.AlphaColor = RGB(255, 255, 255, 0);
temp.SetSprite("sprites/funke.sprite");
temp.Active=true;
temp.Interactive=false;
temp.AttachScript("scripts/staub.script");
Sleep(5);
}

i=i+1;
while (true)
{
staubEntities[i] = Scene.CreateEntity();
temp = staubEntities[i];
temp.X=1280;
temp.Y=Random(450,1000);
temp.AlphaColor = RGB(255, 255, 255, 0);
temp.SetSprite("sprites/funke.sprite");
temp.Active=true;
temp.Interactive=false;
temp.AttachScript("scripts/staub.script");
i=i+1;
Sleep (Random(50,500));
}

it brings the dust to live

second the script for the movement of the created sprites:

Code: [Select]

#include "scripts\base.inc"

var Reg;

while (true)
{
this.X=this.X+Random (-3/1);
if (this.X<500) break;
this.Y=this.Y+Random (-2/2);

Reg = Scene.GetRegionAt(this.X, this.Y);
if (Reg == "strahl") this.AlphaColor = RGB (255,255,255,Random(150,200));
else this.AlphaColor = RGB (255,255,255,0);
Sleep(20);
}

Scene.DeleteEntity(this);

but my dustparticels remain always invisible ....
whats wrong with it ??

by the way what kind of region is the right one (tried both, and none worked) the region for the walkborders(white) or the entityregions (green) ??
and is it possible to get counts below zero with the Random command maybe Random(-5,5); ?!?

as alway thanks for helping so much !!!!

I see one obvious mistake:

Reg = Scene.GetRegionAt(this.X, this.Y);
if (Reg == "strahl") ...

should be

if (Reg.Name == "strahl") ...

"Reg" is a region object, not a string.

by the way what kind of region is the right one (tried both, and none worked) the region for the walkborders(white) or the entityregions (green) ??

We're talking about scene regions, not region entities.

and is it possible to get counts below zero with the Random command maybe Random(-5,5);

Um, you got me here. I think it should work, but better try it But even if it wouldn't, you can always do something like Random(0, 10) - 5.

thanks so far.

now i got it and i am able to check wether the dustparticle is in or out of the region.
but for any reason i dont get them to be displayed when they are in the region

if (Reg.Name == "strahl") this.AlphaColor = RGB (255,255,255,Random(100,255));
else this.AlphaColor = RGB (255,255,255,0);
so they should be visible, but they are not !

i switched the outside particels to visible for testing reason and they work. but when they enter the region they become invisble.....

i do not understand it ??

any ideas ??

ok got it by myself ....
the problem was the position of the region in the layers.
it was under some other pngs so they could not be seen ....

hurray its working now ...

thank you very much
