If you are making a 2D game, you should use this one.

Unity got your back even after 7 years. <3

Thanks! Tip: if anyone is making a platformer and have 2 types of coins/objects that are meant to be picked up by the player/user than you can move this code (oncollisionenter) above the code for the first object OR ELSE it may make the jumping of your object worse.

If this isn't working for you, you may want to try to make the object that is being collided (in this case the prop_powerCube) a prefab.
It wasn't working in my game and after some time of trying different possible solutions, I made the object a prefab and it started working.

Doesn't work. I put a variable in the statement instead though so is this the reason?

[BluWrCk]

Note: This ONLY works if the script is attached to a parent object. Child objects don't seem to want to detect "OnCollisionEnter".

me: ok modified my script lemme playtest it


Unity: nah how 'bout wait 5 minutes m'kay?

[muhammadzaid]

i did the same but i made the cube to stop from the speed of 15 to 0 but the cube is touching the obstacle and coming back like a spring for some seconds the its stopping sometimes its not stopping

[parit]

exactly what I was looking for... thnx Unity

[metamango]

man, I like someone that keeps things simple and no-nonsense.

[nepsis]

Why I can't put another condition ? (like moving forward with "transform.Translate(0, 0, normalSpeed * Time.deltaTime);" )

[needfulsamurai]

What if i want to set it not to the hierachical name "power_cube" but to anything on a special layer?
Is it the same then?

Thanks for any help! ^^

You just solved my problem!!! you are the Man!!! Thank you

[weirdosheep]

The hierarchical name of my object is "Uncle Spleen" which does not trigger the function for some reason. Could it be reading the name wrong because of the space?

[yongamer]

I see many have problems with this. It may be because you are creating a 2D project, then you should find another tutorial. Else, it may be because you miss one of the following: collision detector for obj1, collision detector for obj2 or rigidbody for obj1/obj2.

Thank you i was stuck. I was trying to create a point system based on what the object touched. :)

[BrentVIDSZ]

doesn't work... I try to pick up a medicbox, and it just walks on top of it, the medicbox has the exact same name as I am referring to and they both have a rigidbody( don't know if that's a must), Please help, I need to fix this for a school assignment...

Hello guys, i want to freeze player's Y position onCollisionEnter, how can i write it? Please help me

[microphonebeam]

Why on some functions do you have to use two equals instead of 1?

I am new to unity and do not understand it. Have you any tips or good youtube videos I could know of to improve my basic skills. Creating land and terrain, adding people, guns and making them move etc. Please help, anything useful will do.
