Passable models

Passable models - 10/11/08 18:08

Hi All!

I've made a model with 3DS Max, exported it as .3ds.
It works well except one thing...
It's passable... I do not flagged it passable and use no script to make it passable...

I do not know why but all of my models made by me are passable :S

Please, someone, help me :S

Im not 100% sure on this. But is there a way to set its collision detection ? If so you may wanna look into that. I know from other engine experience, or even working with 2D you need to make sure collisions are set.

hmm, where do you import it, in WED or MED and then WED, when you import your model in WED, you import it as a WED Block and this could be your Problem try to import it in MED and then WED when you havn't done it yet.

I import in MED then WED.

Hmm... But sample models are not passable as default.. :S
Collision detection? Do you mean setting it via script or checking "on" the polygon flat?

I have tried to use the polygon flat but then my model gets in an invisible box. I mean e.g. I cannot get to an inner corner in the garden.

It may be aa big hassle, but I struck this problem too.
I could only get around it by setting polygon ON for the models
and compiling with "create meshes" in advanced compile settings turned ON.

Best of luck, and be prepared for many warnings during compiles.

Re: Passable models - 10/12/08 21:33

I got no warning during compiles.
But my model which is a park with a garage and some lamps, is in a box, I think it's called bounding box and I cannot get in neither the park...

I set the polygon ON and checked the 'create meshes'.
Can my model be wrong? I do not know why :S

Re: Passable models - 10/13/08 13:05

That would be my 'guess', a faulty model.

The bounding box you normally see in WED is just so you can see the models
maximum dimensions, it doesnt actually exist.

Try testing by putting your player-start position inside the box in a
valid place and see if everything 'inside' collides ok.

If it does, there may be some hidden bounding box built into the model.
Open the model in MED, and zoom the 3d view right out. Any bounding boxes
will show here if they exist.

If you know how to post files here, post an untextured copy of your park model.

Hi all!

Me and kronomanta made the model.
Here is the link :

Re: Passable models - 10/13/08 16:06

I put the player-start pos into the box... but my player starts lifting to the top of my entity...
I made the gravity with c_trace, so I think that's why it does the lifting.

I looked at the 3D view in MED but there's no bounding box :S
Szigibence has uploaded the model mentioned...
I hope, seeing it will help :S
Cause we cannot use any of our models :S all of them have this problem :S

Re: Passable models - 10/14/08 09:11

Model contains no problems of the type you describe.
(you may have dynamic lighting issues later due to open meshes though)

I DLed the model, straight import to MED, saved, and loaded as entity
in WED into a pre-existing test level of mine, and set polygon flag on.

It works fine here, I cant get into the park cause of its wall, and cant
get into garage as there are no doors, but Im able to hug the walls
right the way around, and if I place my start inside its all cool.

The problem is somewhere else....

How are you adding the model to WED?
Object / Add_Model, Object / Load_Entity? (same thing)
or as a prefeb or terrain?

Posted By: Kronomanta

Re: Passable models - 10/14/08 14:19

I use Load_Entity.
That huge building is not a garage, it's a warehouse.

In case you put the player-start pos to the park surrounded by the walls, can you walk in the park?
Normally as it would be a simpla block??

I do not use any dynamic lights, just the 'SUN'.

Moreover, when you are outside the whole park, can you get to the corner between the wall of the warehouse and the wall of the park?

What do you use for the gravity? c_trace or something else?
Cause I use

Code:

c_move(my,nullvector,my.move_x,use_aabb | ignore_passable | glide);

for movement and

Code:

trace_mode = ignore_me+ignore_passable+use_box;

for handling gravity.

Do you think the problem is here?

Actually, I use a modified movement code of Kingdom Hearts

But just the movement code

Re: Passable models - 10/14/08 16:01

old manual reference:
c_move
USE_AABB

Quote:

Use an axis aligned bounding box (AABB) for collision, rather than an oriented bounding box (OBB). The AABB system is faster, but ignores the entity orientation on USE_BOX, treats models and sprites as boxes, and requires a BSP level. See collision for the difference between both systems.

*treats models and sprites as boxes
*requires a BSP level
AABB might be quicker than OBB and ent_move might be quicker than c_move with AABB.
OBB, c_move, c_trace, c_rotate only for model only (non-BSP) levels!?

Ahh, OK, I get it now.

I can walk around inside fine, and can enter the little shed-thing in the middle. The shed behaves perfectly for polygon
collisions. ie can walk into-under-backout fine and its 'poles' are solid and un-passable as they should be.

You shouldnt have a problem then.

Yes, outside of model was perfect polygon collisions too.

Code:

trace_mode = ignore_me+ignore_passable+use_box;

for handling gravity.

My testbed is primitive and has NO gravity, everything glued to the floor.
But my movements is controlled by "c_move(my, p_dist_travelled, nullvector, GLIDE);"

Yes I think so. You are using BOX collision detections, AABB instead of OBB, like TestDummy said.

I would suggest replacing your lines of code with

Code:

c_move(my,nullvector,my.move_x,ignore_passable | glide);   //movement
...
trace_mode = ignore_me+ignore_passable;                    //gravity

Let us know how it goes.

Re: Passable models - 10/15/08 14:50

I replaced the code... but nothing happened..
Please, have a look at my player.wdl.
It contains everything from gravity to movement.

Code:

I've got out of the ideas :S

Re: Passable models - 10/15/08 20:43

Ive DL'ed the script, but cant see anything obvious with the naked eye.
It will have to wait till I get home from work tonite to crowbar it into
my testbed level to see whats up.

I'll let you know.

Re: Passable models - 10/17/08 06:03

Got him, simple enough error, leaving in obsolete code when converting away from other obsolete code.

Just change the begining of the handle_gravity function as follows

Code:

FUNCTION handle_gravity()
{
   result = c_trace(vector(my.x,my.y,my.z - my.z_offset),vector(my.x,my.y,my.z - 4000),ignore_me+ignore_passable);
   IF (result < 3) {
   ...etc...

Worked fine for me, even though I couldnt get jump to work.
I have only solved the "bounding box" problem you had, I havent checked any deeper than that.
Best of luck.

Re: Passable models - 10/17/08 18:33

YEAHHHH, We Love You XD
It works fine

except the jumping... but I'll solve it

at least I'll try to solve it

Hehe, as someone in this forum once said,
"The best way to make a character jump is to
sneak up behind him and shout 'BOO!'"

Hope this helps.

Re: Passable models - 10/18/08 19:06

Hehe

He was right

It's absolutely true :D:D

Re: Passable models - 10/20/08 15:09

Ahh... I'm suffering because of the jumping....
I dont know where the mistake is :S
Evilsob, would you check it out if I ask you?

I've run out of my ideas :S

Posted By: EvilSOB

Re: Passable models - 10/20/08 16:34

Yeah, I'll take a look, no promises though.

[edit] Ahhh, my brain is melting....
I dont think I will be able to help, its just too complex. Possibly over-complex.
If you can list and describe the meanings of the movement_modes and
the jumping_modes it may help, but it dont look good.

Re: Passable models - 10/21/08 16:50

Originally, I need a GTA-like controlling system...
and that's the reason I chose the modified Kingdom Hearts code.

But now... I tried to underestand and change how it's needed to be...
So, maybe I'll write a whole new movement system :S using the current camera system.

Re: Passable models - 10/22/08 02:51

probably worth while, the existung system seems overly complex
to re-us if its someone elses.

Posted By: Kronomanta

Re: Passable models - 10/27/08 21:06

Yeah, finally I did it

I can jump perfectly

If someone is interested I'll share the code
