I have made an element and it has a reaction with PHOT and i dont like the fact that the PHOT keeps bounceing off of the element instead of passing through it and actually interacting with it for a bit. How do i make it so that PHOT can pass right through my element?

Lua or c++?

elements.property(x, "Properties", <whatever else> + PROP_NEUTPASS) I think

RedVelvetCake

nah, does nothing.

Ah sorry, I don't do Lua coding, that's just what I could assume from the Lua API wiki page..

Im assuming you replace <whatever else> with any other properties, or with nothing if there are no other properties.

I think its not possible to do it with Lua because all elements that able to pass PHOT is defined here: https://github.com/ThePowderToy/The-Powder-Toy/blob/541417008e082447d47f33a8a529b98a0eed8a7e/src/simulation/Simulation.cpp#L2123

You're both wrong.

You can use the sim.can_move function

While im here could someone tell me why this code isnt working

local isweird = 0
local nearphots = 0

for k, v in pairs(sim.partNeighbours(x, y, 3, elements.DEFAULT_PT_PHOT)) do
nearphots = nearphots + 1
end

if nearphots > 1 then

isweird = 1

end

if isweird == 1 then

tpt.set_property("vy", -1, i);

end

Its supposed to make it so when the element is touched with a photon it starts moving up and wolnt stop until deleted but instead it just jump up a bit and has to be touched with another photon to keep going up.

But how to use that command?
sim.can_move(elements.DEFAULT_PT_PHOT,elements.DEFAULT_PT_DMND)

Does nothing

How to allow PHOT to pass through?
