Hi,
Ive made a my player jump using the 'add force' to the object. But i cant get a precise enough jump for what im trying to achieve.
Im trying to get my player to jump from one platform to another but land exactly in the middle of the other platform (or near enough)
Does iTween offer a jump motion like in my diagram attached(arc shaped)? Or is there another way that doesn't involve iTween?
Thanks
Nick

Im not sure whats the best solution. Ive looked into this post from @jeanfabre
http://hutonggames.com/playmakerforum/index.php?topic=1951.0 (http://hutonggames.com/playmakerforum/index.php?topic=1951.0) but its not quite what im after?
Ive looked over the samples but it mainly covers the 'Character Motor'. Im using 'Add Froce'
I can get near the exact target with just using 'AddForce' e.g. X=130 Y=200, but need it to adjust itself to the exact position before moving again.
Could using 'get' and 'set' position work?
Thanks

Try use a action traslate.
So, when you player jump with add force send event to another state with traslate.position
Note.: check this link and example. https://hutonggames.fogbugz.com/default.asp?W890

Hi xhidnoda,
I have taken a look at the example and im not sure as to where to find the example within the project file you are referring to?
is it the one under the 'Jump Game' and under the player object FSM?
Thanks
Nick

Just follow the instruction below.
When you have the example in your project, open scene of jump game.
Send image if what your don't understand.

Hi xhidnoda,
I have attached a screenshot of my game along with the screenshot of the example game link you sent.
I cant get my head around what to setup from your suggestion....
'So, when you player jump with add force send event to another state with traslate.position'
at the moment the player jumps and lands e.g. from 0.00 > 1.98 (approx) on Z axis
How do i use 'translate.position' to finish moving the character once the player is done? so the '1.98 is 2.00'
e.g. i always need the player to jump forward and land 2.00 along Z (local) axis.
Sorry if i doesn't make sense. Could you please provide me with an example? would be most appreciated

Hi im just replying again bit i stumbled upon an example online which use Parabola. Seems like the principle im after in playmaker, but wanted to avoid scripts.

Hi
Let me see...
I'm think you don't use a add force Z axis to move your player. (Have you know the coordinates of 3D?).
In the example the player use add force to jump in the Y axis...right? So, use Y axis to jump.
Add a new action to Jump state. The action "Traslate" and set the X axis to "how far to go the player when jump in the X axis".
1. Jump with add force in Y axis (add force - action)
2. Traslate the player when don't grounded yet in X axis. (traslate - action)

Hi,
The co-ordinates are from self position 0.00 and to 2.00
The reason i cant use world position is that the character is controlled that way.
Right, i understand what you are saying in your 2 steps. But how do i use '(add force - action)'?
..............................................................................
I found this script which looked ok (but doesnt jump smoothly). Can this be made with playmaker?
using UnityEngine;
using System.Collections;
public class jump : MonoBehaviour {
public float forward, up;
public float maxForward = 10, maxUp = 10, speedForward = .01f, speedUp = .01f;
public bool jumpBool;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
if (Input.GetKeyUp(KeyCode.Space))
{
jumpBool = true;
}
if (jumpBool)
{
if (forward <= maxForward)
forward+=speedForward;
if (up <= maxUp)
up +=speedUp;
transform.position = new Vector3 (transform.position.x + forward, transform.position.y + up, 0);
}
}
}
Sorry for all the questions.

your game is a 3D camera or 2D camera?
-
3D camera.... im making a 3d game but its just a jump moving along one axis (z)
-
So?...you can make this work?
-
Still working on it. Haven't had time to test. Ill try it tonight.
-
I works ok :)
Just struggling to get all the script recreated in playmaker, the code below is what im struggling over.
transform.position = new Vector3 (transform.position.x + forward, transform.position.y + up, 0);
Any ideas?
Nick
-
Make 2 variables (forward and up as Float)
Set the forward value = 5 (just example)
Set the up value = 7 (just example)
Use translate action
Set the x axis to forward variable
Set the y axis to up variable
Test.
-
Hi
Thanks, ive used the 'translate' action
I think ive done this part of the code wrong now lol
if (forward <= maxForward)
forward+=speedForward;
if (up <= maxUp)
up +=speedUp;
Do i use a 'FloatAdd' for the speed? or just use 'FloatCompare'?
or have i got the wrong idea?
thanks again
Nick
-
both action.
for this: if (forward <= maxForward)
use: FloatCompare
for this: forward+=speedForward;
use: FloatAdd
As for the rest.
-
Thanks! I'll give that a test

Hi,
Ive had a go and i think i must be doing something wrong? The player jumps to the location but when falling it doesn't move smoothly?
attached my setup.
thanks again
Nick

Hi
I don't understand what is the problem here.
Your player jumps in the location rigth?
But when is falling doesn't move? this is the problem?
-
hi,
The player jumps and lands in the location.
The problem is when the player is falling down (dropping) The player moves (shakes/wobbles) when falling.
something must be setup wrong with my FSM?
attached a video of how it behaves.

don't not really why happen this. :o
Sorry can't help you on this.

Hi xhidnoda,
I had a bit of luck and i fixed the issue with the shake/wobble. I noticed that the original script used a Vector3 and applied my own in playmaker. Now it works :)
Demo:
https://www.dropbox.com/s/l9qfwgpru9nt1tf/bounce003.avi (https://www.dropbox.com/s/l9qfwgpru9nt1tf/bounce003.avi)
but now i have an issue where my player doesnt bounce to my exact location i specified in the 'forward' float.
e.g. i setup the 'forward' (Z axis) to be (2.00) but my player jumps to e.g. (2.10003) instead
Any ideas?
Could i somehow Clamp it at 2.00? Maybe a FloatClamp or Vector3Clamp? not sure as ive never done this before.
OR is there a calculation i could do to work out the end position of the jump? maybe by using the floats i have already...
My Floats are:
- forward
- SpeedForward
- MaxForward
- Up
- SpeedUp
- MaxUp
Thanks, hope im making sense.
Nick

Hi
Yes use Float Clamp to specific how far go your player when jump (z axis)
-
Hi
That's works. But sometimes the player stops at 1.9999 instead of 2.00. Other times its over e.g.2.1
My setup is minimum=2. maximum=2
Could this be the player sliding?
Thanks again
Nick
