Layla has recently commented on how better and more customizable sound mechanics is something he/she is interested in, so even if a portal mechanic needs to be implemented by the community, the prospect of sounds and even voice being properly transmitted through them is still there, which is nice.
As to how this could be implemented if not directly by FP: Maybe if map geometry is editable during play, you can carve a box on the wall where the portal is shot and create a special shader to properly render the other side even if you are standing halfway through it.
I disagree, S&box (or even Garry’s Mod, to a lesser extent) is definitely about portals, simply because portals are a thing you can create. Same goes for flying machines, player customization, roleplay, melonbomber, etc.
What @Tastandut is basically asking for is that, since the mechanic he is interested in requires physics and geometry to play nice with him, support might have to be build in at an engine level to make this reasonably performant, specially if you want to be able to stand between portals, and not simply teleport to the other side when you touch a wall.
Não tem nada escrito nas regras de conduta do forum falando sobre manter as discussões em inglês (que bom!), e sinceramente, essa expectativa de que discussões devem ser feitas na sua lingua nativa é algo que somente pessoas que falam inglês como primeira lingua possuem, o resto entende que o munto é muito pluralizado pra isso que acomodações precisam ser feitas. Se você deseja que seu post atinja a maior quantidade de pessoas possivel, talvez você deva excrever em inglês, mas isso é algo totalmente opcional.
If a language restriction is put in place, I will abide to it, but if not, it takes 2 seconds and we do it all the time.
