altar clickable from 1 direction only

[Granamir]

Hi everyone,
for my flying bookshelf i had to use altar (click max distance = 1) but now, that it's almost complete, i realized that i can reach it from his back side too, turning it in a complete sh...
So, anyone has an easy way to make it clickable only when party is in front of it?
My actual solution (still an idea) is to check party position and enable clickable component only when champions are in front of bookshelf, but it's a bit tricky, i'd prefer a cleaner solution.
Any help?!

frontFacing = true on the ClickableComponent will only allow it to be clicked if the party is facing the same direction as the object.

TY minmay, u saved 2 weeks of my work

...but unfortunatelly it works for taking items, if i try to put them nothing happens (except i throw item)

Do you have it placed on the floor, or on the wall?

[Granamir]

floor

I'm pretty sure ClickableComponent won't change taking items at all - items in surfaces are picked up normally (since they're on the map) except that the player must be on the same square as the surface. ClickableComponent is for adding items to the surface.
It's really hard to tell what you're actually trying to do, I think you'd have to share your model at this point.

[Granamir]

Sure.
Here is my files: https://onedrive.live.com/redir?resid=d ... file%2czip
Unzip, put models in mod_assets/models and objects.lua file in mod_assets\scripts (or rename it if u don't want to overwrite your file).

btw i made a bookshelf with castle walls, with 2 surfaces and clickable components, so i can't stay in same square of object, that's why i used maxDistance = 1, but this makes clickable components reachable from all 4 sides, so i added frontFacing = true but seems clickable is not more reachable from any position.
With model and code it would be more clear i guess.

if u just want to see my code without downloading anything here it is:

Okay, I see what you're trying to do now. Since you already have the onAcceptItem hooks, the easiest way to fix this issue would be to just return false from both if the party isn't facing the correct direction.
The throwing behaviour is inherent to obstacles. The only things that prevent throwing are solid tiles and secret doors. You can always throw items directly at adjacent obstacles, and always will throw the item if it doesn't go into a surface.

[Granamir]

Ok working on it. TY minmay.
Btw why frontFacing doesn't works?

[minmay]

It does work, it does exactly what I told you it does. But it won't help for your case because you have two clickable components that you want to be clickable from different directions.
