can someone explain me this one line code
this code is about raycast.
Physics.Raycast(transform.position, -Vector3.up * gravity, distToGround + 0.1f
as far i know raycast have starting point , direction and hit distance.. is disToGround + 0.1f hit distance.?? can anyone explain me in brief. Physics.Raycast(transform.position, -Vector3.up * gravity, distToGround + 0.1f
Well, first off, the example you provided isn't the entire function call.
That aside, as you said, the third argument is the distance; rather, it's the maximum length of the Raycast(). distToGround is a variable someone made for the call, so the intent with this particular Raycast() is to check from the character's position toward the ground (with a gravity modifier, presumably 1 or -1 in case gravity is reversed in the game's context), up to a maximum distance (distToGround) to determine whether the character is standing on the ground.
Edit: Furthermore, the + 0.1f is there for padding. If you have a capsule collider character with a center 1 unit from the ground, then fire a Raycast, a 1.0-length Raycast has a chance of unexpectedly falling short due to rounding errors, whereas 1.1-length, after adding the padding, ensures it will hit the ground more reliably.
thanks a lot. @$$anonymous$$o-$$anonymous$$haon but i dont know what's wrong in my code still i am not able to get desire answer. i have animation of landing and i want animation to get triggered as soon as my character reach certain height. but nothings happens. ins$$anonymous$$d my character jump at height and then get stuck mid air and the stuck pose moves mid air by "vertical" and "horizontal" keys. is something wrong with this code. i know it is just the snippet of the code. if you need i can post the full code. void jumpDown() { if (Physics.Raycast(transform.position, Vector3.down, height)) { anim.SetBool("jumpDown", true); } else { anim.SetBool("jumpDown", false); } }
