(trash, do not read) - mrpin355 - 03-31-2018

While this thread is active.

I got a issue dealing with Wiggler's body parts, and I seriously want help, the fact that I tried many methods but it won't work and "Developer Discussion" is the least active thread of this site.

The problem is that whenever it instantly moves horizontally 8 pixels, specifically, shifting itself while on the slopes it jumps *number depending how steep the slopes is* pixels up,
I know why that happens, but I need a better method that solves this problem.

Here is a screenshot visually portraying it:

Wiggler is flashing

Thanks.

Some more information would help in diagnosing the issue. What kind of collision checking are you using?

I use collision_rectangle for these situations.

Please post your codes here using

RE: Wiggler's body parts on slopes - mrpin355 - 04-02-2018

Before reading the code, It's a modified Hello's Wiggler object.
I might hear I should make my own.

Stun code

Code:
//Stop body parts
   for (i=0; i<maxpart; i++) {
   
       //Affect parts animation
       with (part[i]) {
       
           //Freeze
           image_speed = 0;
           hspeed = 0;
           
           //Stop turn sequence
           timerstart = 0;
           
           //Snap the parts
           x = behind.x-offset*xscale;
           
           //Turn him into a "accordion"!
           offset = 3;
       }

Slope logic

Code:
//Embed into the slope to ensure correct slope mechanics
if (collision_rectangle(bbox_left,bbox_bottom,bbox_right,bbox_bottom+4,obj_slopeparent,1,0))
and (!collision_rectangle(bbox_left,bbox_bottom-4,bbox_right,bbox_bottom-4,obj_slopeparent,1,0))
and (vspeed = 0)
   y += 4;

///Handle slope collisions
if (collision_rectangle(bbox_left,bbox_bottom-4,bbox_right,bbox_bottom,obj_slopeparent,1,0))
&& (!collision_rectangle(bbox_left,bbox_bottom-8,bbox_right,bbox_bottom-8,obj_slopeparent,1,0)) {

   //Stay embed on the slope.
   while collision_rectangle(bbox_left,bbox_bottom-4,bbox_right,bbox_bottom,obj_slopeparent,1,0)
       y--;
}

When spawned

Code:
//Create anatomy
part[0] = instance_create(x,y,obj_wiggler_body) {

   part[0].image_index = 0;
   part[0].depth = -1
   part[0].parent = id;
   part[0].behind = other.id; //Snaps to the head
}
part[1] = instance_create(x,y,obj_wiggler_body) {

   part[1].image_index = 1;
   part[1].depth = 0
   part[1].behind = part[0];//Snaps to the previous body and so on.
   part[1].parent = id; 
}
part[2] = instance_create(x,y,obj_wiggler_body) {

   part[2].image_index = 2;
   part[2].depth = 1
   part[2].behind = part[1];
   part[2].parent = id;
}
part[3] = instance_create(x,y,obj_wiggler_body) {

   part[3].image_index = 3;
   part[3].depth = 2
   part[3].behind = part[2];
   part[3].parent = id;
}

If you need more, let me know.

Anyone here?

Comment out this in the stun code:

Code:
x = behind.x-offset*xscale;

It makes the body part snap to it's assigned behind body parts.
Functions purpose is when it's stunned or when it makes a turn.
'offset' means the width of the body.

RE: Wiggler's body parts on slopes - Hyper - 04-07-2018

You intended to make the Wiggler to shorten itself when hit, however the y position is not set during the processes. I would recommend to do this:

Instead of:

Code:
//Snap the parts
x = behind.x-offset*xscale;

//Turn him into a "accordion"!
offset = 3;

Do this

Code:
//Turn him into a "accordion"!
offset = 3;

//Snap the parts
x = behind.x-offset*xscale;

if (collision_rectangle(bbox_left,bbox_bottom-4,bbox_right,bbox_bottom,obj_slopeparent,1,0))
{
   do
   {
       y--;
   }
   until !(collision_rectangle(bbox_left,bbox_bottom-4,bbox_right,bbox_bottom-1,obj_slopeparent,1,0))
}
else
{
   do
   {
       y++;
   }
   until (collision_rectangle(bbox_left,bbox_bottom-4,bbox_right,bbox_bottom,obj_slopeparent,1,0))
}

Thanks, but for some reason GameMaker reads it as 'Unexpected symbol'.

RE: Wiggler's body parts on slopes - Hyper - 04-07-2018

Are you using Game Maker 8, Studio, or Studio 2? Is there a reference that points out the unexpected code error?

I'm using Studio 1.4 and it doesn't point out why.

RE: Wiggler's body parts on slopes - Hyper - 04-07-2018

Let's see if this helps:

Change this:

Code:
until !(collision_rectangle(bbox_left,bbox_bottom-4,bbox_right,bbox_bottom-1,obj_slopeparent,1,0))

To this:

Code:
until (!collision_rectangle(bbox_left,bbox_bottom-4,bbox_right,bbox_bottom-1,obj_slopeparent,1,0))

until (!collision_rectangle(bbox_left,bbox_bottom-4,bbox_right,bbox_bottom-1,obj_slopeparent,1,0))

Unfortunately, it still doesn't work.
I recommend you test it before you publish the code.
If you want, I could PM and give you the object and diagnose it.

RE: Wiggler's body parts on slopes - Hyper - 04-08-2018

I am currently using Game Maker: Studio 1.4.1804. I have tested out the code without any issues:

Some older version of Game Maker Studio may have issues like this, please update the game engine and see if that helps.

I'm using 1.4.1804 as well.
Wtf is going on?
Like, did I accidentally do a minor change?

RE: Wiggler's body parts on slopes - Hyper - 04-08-2018

Clear its compiler cache and restart the program would be a typical solution in most cases.

Sorry for annoying you, but this time the problem is fixed!

Thanks for helping!
Topic disclosed.

for now...

Since I am not able to DM you (Error message: Existant has private messaging disabled. You cannot send private messages to this user.), I'll just post an alternative solution here:

Code:
if (collision_rectangle(bbox_left,bbox_bottom-4,bbox_right,bbox_bottom,obj_slopeparent,1,0))
{
  do
  {
      y--;
  }
  until !(collision_rectangle(bbox_left,bbox_bottom-4,bbox_right,bbox_bottom-1,obj_slopeparent,1,0))
}
else if (collision_rectangle(bbox_left,bbox_bottom+1,bbox_right,other.bbox_bottom+32,obj_slopeparent,1,0))
{
  do
  {
      y++;
  }
  until (collision_rectangle(bbox_left,bbox_bottom-4,bbox_right,bbox_bottom,obj_slopeparent,1,0))
}

And this time it worked!
Thanks for your big help!
I was trying to fix that problem like in 2 months!
