I found a problem, the character moves to shoot even though I use the lepr code. How can I fix it?
So when you press a key i assume A or D you are shooting ? from what i can see i am guessing there is another script on character, that use the same keys (A or D) then is shoots. Your question is a little hard to understand is it movement problem(like sliding or teleport) or wrong behavior(shooting) ?
Ok somthing like this then ?
new Vector3 NewPos;
// Update is called once per frame
void Update ()
{
if (Input.GetKeyDown(KeyCode.D))
{
NewPos = transform.position;
NewPos.x += 5;
}
transform.position = Vector3.Lerp(transform.position, NewPos, 2f * Time.deltaTime);
}
}
See what you are doing is trying to move withing 1 frame when you press A||D. This way its doing it over many frames so its smooth but this way has an issue of rounding. You see LERP will goes towards target but never gets there 0->5 (Look in the inspector and you will ses what i mean). Now you can Code in Snap function so when object gets close to target position you can force it so from 0.49 to 5. This is how i fix it. Hopefully this helped you @spigo98 a little.
The problem is that when I press A or D doesn't a fluid motion
Hello, sorry for a bit late response, but it's now that I'm working on a endless runner game for a school project.
I'm also posting this for anyone else who is checking the forums that might be having issues with this case and could benefit from my input, since I've looked and found an answer to my problems countless times and I just want to return to community.
I've written this code for moving a character quite smoothish(probably could be even smoother) from point A to B and B to C and vice versa . This code also responds if a player wants to change direction of character when its already moving towards a certain lane. For example he wants to go from lane A to B but while character is moving to B he wants to go back to A. I hope this will help u in anyway.
//This is all in Update Function
// I have a 3 lane runner { -1, 0, 1 }, checking so it doesn't gets over that

//bool centeringZero is necessary to prevent update of doing a multiple movement changes at once, since update is a bit unpredictable and same thing can be set multiple times. So I find bools quite useful in Update functions.

If you want smoother transitions from one lane to another, only thing that could be causing uneven transition is when function fixes character position to its lane. You can play around with if statements where it checks if its close to desired character X position and then set its position.
//try changing this to even closer to horiDiff, perhaps 0.01f - could be better but not sure
if (transform.localPosition.x < horiDiff && transform.localPosition.x > horiDiff - 0.1f && !centeringZero)
{
Vector3 fixX = transform.localPosition;
fixX.x = horiDiff;
transform.localPosition = fixX;
currRow = 1;
centeringZero = true;
Debug.Log("centering " + horiDiff);
}
I've tried to explain the code and logic best as I can, but if there is still anything unclear, please tell me where and I'll try to explain it as best as I can. Again this could be probably done smoother/better and definitely cleaner, but I'm kinda rushing to finish it as fast as I can, since project due is closing in fast, so this will work for me.
