Add Force 2D makes object go through collider (SOLVED)

[Just]

How do I stop that happening?

Add a collider to object?

Hi,
Could you give some more information (pictures/videos)

Some reason could be that if the speed of your object is very fast,
that it "jumps over" the collider a solution could be to slower the speed or make the collider bigger, there is a edit collider button on the collider component so you can resize it without resizing the object

I recorded video how it works for me currently. What I didn't mention in my video both playable character and everything in level has collider. In 1:23 mark it shows the problem, I also did some explaining about my project in the beginning of video.

Let me know if you need more information.

Hi,
the ad force is a low number but that does not mater,
it is how much you object is moving per frame that might cause not seeing a collider.

What kind of colliders are you using on the character and on the floors?
(box,sphere,edge...)

Maybe you can use a "raycast" upwards before jumping and when there is an obstacle don't do the add force?

It seems using Raycast 2D underneath platform solved my problem neatly 

Thank you everyone!

EDIT: Oh yeah, and those with similar problem reading this later: put negative number in Y for Raycast to stop Add Force going through platform (just 0 won't do anything).
