I find myself with the need to use a specific shape to detect certain objects and materials (labelled) in my current project. The shape I'm looking for, in particular, is a prism with a base which has two straight lines and one curve one as sides: basically, it's a slice of a cylinder, a 'slice of cake' if you want. In LittleBigPlanet 3 (technically possible also in 2) I had two options to achieve this: either 1) use the tag sensor with an angle limit, which would result in a 'slice of cake' sensor range shape, useful for tags, or 2) a slice-of-cake shaped hologram material object with a impact sensor set to 'include touching' (this made the impact sensor detect things even on a material without physics such as the hologram: it would turn on when objects passed through the hologram shape, which is exactly what I need to do).
Now in Dreams, neither methods work as far as I've tried. The tag sensor method would use trigger zones, and while there are a lot of shapes available there is no way at the moment that I can see to choose a slice-of-cake shape for the trigger zone. Even just a specific part/section of the cylinder trigger zone shape would be enough for what I need to do but I haven't managed to find a way to tweak the trigger zone in order to have such a shape. The only idea I've had is using multiple trigger zones with cube shapes to 'cut' a main cylinder shape trigger zone and using and and not gates to achieve the corret detection output; however, I'd like to avoid doing this since in the final level there would be dozens of instances of this logic working at the same time, and making multiple 'slice of cake' zones of limited size would
I haven't found a way to replicate the hologram method as well. The Impact Sensor in Dreams lacks the 'include touching' functionality that the Impact Sensor had in LBP2/3, or better it does not work the same as it did in LBP. Specifically, the impact sensor does not work at all with objects that are not movable and/or not collidable: no one of its four outputs send signals when I have another, physical object go through the 'hologram like' object
If you have any ideas how to achieve this kind of custom detection with different 'trigger zone' shapes it'd be very appreciated, it's basically mandatory for my current project. Thanks!
