Looking for a solution

[brokk]

Hello. I need some help. I have a showImg shadow and I want it to follow player and it does. But the problem I am running into is when the player jumps, the shadow also follows the player's y value so there is no sense in depth when jumping. (Keep in mind player can move in all 4 directions just like default movement.)

So I come to you forums in need of help.
Some information on the jump action:
The player's y value goes -0.5 when jumps for a time of (0.5)
The player's y value goes +0.5 when falling for a time of (0.5)
So the jump is (1) total in time.
The Jump and Fall are just ran through a looping script.

Jumping works perfect, the shadow just doesn't like to.



I've tried:
1. Keeping the y value at one point once the player has left the ground.
Problem: When you move up or down while jumping, the shadow
jumps when you land.

2. A bunch of sleeps();
Problem: Glitchy

3. A butt load of scheduleEvents()
Problem: Even more glitchy.

PHP Code:

//#CLIENTSIDE
function onCreated(){
 setTimer(0.05);
 }
 
function onTimeOut(){
 setTimer(0.05);
//SHADOW
 if (player.canjump = true){
//THIS IS WHERE PLAYER IS ON GROUND. WORKS FINE
  showImg(20, "shadow.png", player.x+0.5, player.y+1.5);
  changeImgVis(20, 1);
  findImg(20).layer = 0;
 }
//PLAYER IS IN AIR HERE, BUT TOOK OUT WHAT I HAD
 if (player.canjump = false){
 }
}



function onKeyPressed(code, key){
 if (key == "s"){  //'s' JUMPS. THE ACTION IS DONE ON ANOTHER SCRIPT
  if (canjump = true){
  //I DONT KNOW WHAT TO DO HERE. I TRIED A LOT AND FAIL EVERYTIME
    showImg(20, "shadow.png", player.x+0.5, player.y+1.5);
    changeImgVis(20, 1);
    findImg(20).layer = 0;
    //DELETED IDEA
    }
   }
  }

The player's z property changes when jumping (I believe) so try changing the z property of that image object to match the player's z property.

I've never messed with any Z values... You may have to go more in depth with me... I'm sorry

Take a look at the changeimgzoom(id,factor) function.

Though that will make the shadow smaller, it will not change the distance from the player and the shadow when jumping.

Ah ok then what you want to mess around with is the player.z variable. It's exactly what you want I think.

first off: why are you using that kind of shadow instead of the default one in the ganis?
seccond thing: watch your if() statements

Because I need the shadow to display a "sense" of depth. If the shadow stayed with the player, it would just look like the player is rolling up and down..

To clarify, he's talking about stuff like this:

PHP Code:

 if (player.canjump = true){ 


A single equals sign is used for assignment. A double equals sign is for comparison. GS2 tolerates misuse to some degree (it shouldn't...) which is why your script still works, but you should instead do:

PHP Code:

 if (player.canjump == true){

Yeah I fixed the 'if' statements. But I still can't find a solution to my problem

Have you tried using the player.z variable for your jump?

This is something that could work. Not 100% sure but I can't see something wrong

PHP Code:

//#CLIENTSIDE

const JUMP_HEIGHT = 1; //Player can jump one tile high

function onKeyPressed(code, key) {
    //Won't change the player.canJump as you could keep it as a check
    //If the player could jump in theory for other scripts
  if (key == "s" && player.canJump == true && player.z == 0) {

      //Create the shadow image
    showImg(20, "shadow.png", player.x+0.5, player.y+1.5);
    changeImgVis(20, 1);
    findImg(20).layer = 0;
      
      //I rathered to make it into one for() loop and have if statements
      //Inside of it instead of creating 2 loops, probably just a personal
      //Preference
    for (temp.i = 0; temp.i < JUMP_HEIGHT*2; temp.i += 0.05) {

        //Since i took the JUMP_HEIGHT times 2, I can create such a check
      if (temp.i < JUMP_HEIGHT) {
        player.z += 0.05; //Move the player up
      }
      else {
        player.z -= 0.05; //Move the player down
      }
    }

      //failsafe reset the player.z
    player.z = 0;

      //hide the shadow as you will probably move back to the original one
    hideImg(20);
  }
}

I had just read read this this morning but I figured it out last night! thanks though!

I just simply change the z value of the player and the shadow stays at (player.x), and (player.y-player.z)

Works like a charm. I never knew about the z factor til yesterday so I would like to thank you graal forums for making life a lot easier on me lol
