How do I repeat for each instance of a certain condition

So I have plants and when they're fed upon they lose food value until they disappear, the problem is I can have 5,10,20 a million animals eating them and they still only lose 1 food value per second. What I have looks like this

Every 1 second : Plant subtract 1 from foodvalue

Animal is overlapping plant : Animal add 10 to food

system For each animal?

I tried that but then it does it for every animal overlapping a plant even if it's a different one like if there's 3 plants and 5 animals on one, 3 on another and none on the third they all 7 from their food value every second (I'm using families for the animals and a single sprite for the plant if that would affect it at all)

should work if your event is correct..

You should reference both the animal and the plant in your event..

Ok when I put for each animal before if it's overlapping the plant it worked. Thank you

solved.

Yeah although now I'm having a different issue. There are trees and bushes. Only bigger animals should be able to eat the trees so I have

(Every 1 second, for each tree, animal is overlapping tree, animal.height is greater than 50, animal is not full)

[Animal add 25 to food]

This works but if an animal large enough to eat a tree is eating one then if a small animal is overlapping the tree it also starts to eat it. I know sometimes the order of conditions can affect it, do I need to change that? Or am I just missing something

Seems like you would want a for each animal, instead of a for each tree, but I might misunderstand the event..
