Fixed.

You pretty much hit the nail on the head, there.

I [i]think[/i] I've found the culprit: the styles' ordering between [url=https://github.com/rheit/zdoom/blob/master/src/p_acs.cpp#L3537]LegacyRenderStyleIndices[/url] array and [url=https://github.com/rheit/zdoom/blob/master/src/r_data/renderstyle.h#L39]ERenderStyle[/url] enum doesn't match, which [url=https://github.com/rheit/zdoom/blob/master/src/p_acs.cpp#L3612]SetActorProperty appears to rely on[/url] when setting the appropriate renderstyle.


That or I have no idea what I'm talking about. Although, I ran the same test file above with a custom build I compiled which fixes the ordering, and it seems to produce correct results.

Script "ChangeRStyle" (void)
{
  int rstyle = GetActorProperty(0, APROP_RenderStyle);

  If(rstyle == STYLE_Translucent) SetActorProperty(0, APROP_RenderStyle, STYLE_Stencil);
  Else SetActorProperty(0, APROP_RenderStyle, STYLE_Translucent);
}

Tested with:[list]
[*][git=67c6690][b]2.8pre-495-g67c6690[/b][/git] (broken)
[*][git=3f8c723][b]2.8pre-420-g3f8c723[/b][/git] (works)[/list]

In the attached file below, there is a simple actor with renderstyle translucent, which calls an ACS script that is supposed to change its renderstyle from translucent to stencil and back to translucent. Here is the script:

[code]
Script "ChangeRStyle" (void)
{
int rstyle = GetActorProperty(0, APROP_RenderStyle);

If(rstyle == STYLE_Translucent) SetActorProperty(0, APROP_RenderStyle, STYLE_Stencil);
Else SetActorProperty(0, APROP_RenderStyle, STYLE_Translucent);
}
[/code]
However, when tested in game, the actor changes from its preset renderstyle (translucent) to what I think is shaded, and then to stencil.

My only guess is that something probably went wrong [git=30f57c0]here[/git].
