It is that time of day again to ask for your help !
I do not understand what is going on with collisions in unreal.

I have attached a box in my turtle character so i can detect collisions between her and my hero. (second one is to detect if my hero is falling on top of her).
My hero capsule is set to vehicle (don’t ask why!)
as you can see from picture i have set on purpose to block vehicle category so i can have a visual of what is going on because with overalap i could see it firing all time in BP but i couldn’t figure out why.
When i start

game after approx 2 seconds collision box of my turtle blocks me and hits me even across screen!it is like it’s expanding.
Any ideas of what is going on?
Thank you

I’m not sure exactly what is going on there, for questions like I’d really start a new separate thread in Blueprint section to get more eyeballs, but as a first glance to get more information, try typing ‘show collision’ or ‘pxvis collision’ into console during PIE. will show current collision shapes (from Unreal’s POV or PhysX’s, depending on command), which can be super-useful for debugging collision/character movement problems. You can turn on right at start, and watch what happens with turtle collision shape, which may give you a clue as to what is going wrong.

Edit so i wont create another post:
Do collisions work in flipbook?
I have created a BP with only a flipbook animation and a box for detecting when my player is in close proximity to them so i can activate them.box trigger works wonderfully.
My problem is that although i have set up all my spear-trap sprites with appropriate collision box(in case shrink wrap) activating collisions in flipbook inside BP does nothing.I have even set it up to block all and my player runs right through them.
Is there a way for flipbook to take into account sprite collision box so we can have pression collisions for static objects?
Because my spear-

trap moves up and down it makes no sense to add a capsule or a trigger box since size changes every frame

but if flipbook took account of individuals sprite collision box that it is inside it then everything would work perfectly!

No, flipbooks do not have any kind of collision right now. You’ll need to team a flipbook component up with another collision component such as a box or capsule to get collisions.
