Ultimate Collision Model Sticky

Ang88 · Post by **Ang88** » Mon Apr 05, 2004 8:42 pm

Since there are so many stickys for collision models, i decided to combine them into one.

Tutorial for stretching the collision Models
ALL CREDIT GOES TO XORANGE FOR THIS

As I said before, the "panels" used to be the log, which is tree_leafy_fallentunk.
I just renamed everything so that it would be all "authentic".
I used the scenery, model, collision model & appropriate bitmaps.
(I used Milkshape3D to modify the model & Photoshop for the textures.)

Here's the deal with the collision model....
I have limited knowledge of the collision models and it took me quite a bit of research and experimentation to get to the point I'm at.
I have not yet been able to modify this much more than I already have,but I am still working on it.
(I recommend extracting the "panel" collision model meta and taking a look at it in a hex editor. It would also be helpful to extract the log collision model meta frrom a clean cache so you can compare the two and see what changes I made.)
Basically, down at the bottom of that meta there are 8 packets of numbers that represent vertices for the collision model.
(Beginning at 0x269EE30)
Here's what the first packet looks like:
9AEBACBF CA6B9DBE 62F58F3E 04000000
The first three numbers are floats, and are x,y,z coordinates, respectively.
The last number is just the number of the point. So, this one is vertice #4.
To stretch the verts out to where I wanted them I multiplied each Y coord 5x for each set of verts.
That almost did the trick.
Now, near the middle of the collision model meta there are 6 more important packets of data (each 0x10 bytes), which I believe are all floats, beginning at offset 0x269EC08.
I believe these numbers are attributes of the collision model.
The one's I changed are at the end of the 3rd & 4th packets.
The specific floats I changed are @ offsets 0x269EC34 & 0x269EC44.
I'm not exactly sure what these are, but I know that they affect the surface of the collision model. I multiplied them 5x.
Done. That's all I did to the collision model. Multiplied 10 floats by 5. Whee!
I have experimented with making the collision model thinner, wider, etc. with some success.
I have not yet been able to stretch it along the X axis, otherwise I would've made some giant flat platforms.
I have obviously successfully stratched it along the Y axis, though for some reason I can't make it as long as I want...there is some sort of limit that I haven't been able to get past yet.
I have also successfully stretched it along the Z axis, which I haven't really found a use for yet. If you stretch it along Y & Z you end up with a big block. woohoo, right.
This is a pretty simple collision model. Most of them are not as simple because they have more parts.
As UberJim mentioned, you could probably use a diff. collision model and get similar results. Yes, you probably could, but keep in mind that diff. collision models have dff. attributes. For example the door_blast_collision allows you to shoot through it but not walk through it. Thus if you used something else like that you might need to modify it further for it to suit your needs.
You could also use this collision model with another flattened model if you want.

Ok..that's about all I can think of to say about that.
I hope it was helpful.

I know the value for 19, it's a second variety of flood skin, the two have slightly different blood splats. And change green blood too flood blood. Even though, technically it's not blood. And...be more specific with the just plain:blood, it's human blood. and.....change all the bloods too "skin", cause technically the blood itself is just a bitmap. ok, I'm done. I just wanted an excuse to post, lol.

good job. that helps alot. thanks

Edit: Woah, Woah, Woah... hold on here. on #31.... Glass???? could it be? would that... make things.... breakable?!!?!? YAY! i have the solution to my stack mod!!!!! THANK YOU!

If i followed thi right you can enlarge objects by editing thier hex does this mean you could enlarge a vechile such as the peli?
To the extent so it can hold a tank?
In this case then can you help me by reading my "Peli that can hold a scorpian tank thread" sumthing like that anyway plz help it would be great to see a pelican with a tank firing from the inside.l

Danke · Post by **Danke** » Sun Apr 18, 2004 5:52 pm

It only changes the collision model. You'd have to do that and milkshape it bigger to make it all good. And then I think the tank would fall out.

I really really really need the Pelican in deathisland mod, can someone help?

Bonus Onus · Post by **Bonus Onus** » Fri Apr 23, 2004 8:19 pm

i have the plugin, but i am still not sure how to make something, like a vehicle have no collision model at all, i.e. like it isnt there.

unrelated question: does the thing that destroys the jackal's shield have to do with collision model? because i tried to replicate it for different shields to no avail.

well if it was possible to make a secondry fire that changed the conlision moddle so it made the back close

I PMI'd the platform into a map from blood gulch...but it has the model, but the regular collision model...any idea whats wrong?

Deadly_Shadow · Post by **Deadly_Shadow** » Fri Apr 30, 2004 7:12 pm

I also noticed that there isn't really a tutorial for changing collision like in log mods - I just made one for you guys:

1. Open Halo Map Tools V3

2. Go Under Collision Model

3. Select "scenery\trees\tree_desert_whitebark\tree_desert_whitebark"

4. Don't select Recursive - Only Save Meta - Save it to your Desktop

5. Open "tree_desert_whitebark.coll.meta" in a Hex Editor

6. Find the last frame ( For Example - frame tree whitebark )

7. After it you should see several Reflexives that end with the same 2 Bytes

8. Find the last one of all the of Reflexives there

9. Reverse Endian - Subtract Map File Magic

10. Open Blood Gulch in a Hex Editor

11. Go to that offset you got from Halo Map Tools V3 by Reverse Endianing and Subtracting Magic

12. That is the Collision for the Model

13. Move the Hex Editor Text Line over so the Hex looks like this:

14. We do this to see the X - Y - Z of the Collision Model Easier

15. X = Left & Right - Y = Depth - Z = Up & Down

16. Suppose you changed all Y coords to FFFF FFFF - Then the Model should be wider, have more depth, etc.

17. Try seeing the number as a float by highlighting the 4 Bytes and seeing the float number for X

- Notice the first X Coord and the next X Coord for a Model is first let's say -1.3 and then next is 1.3

- They are making the Left & Right

I seriously doubt that you know ANYTHING about modding.

ok, back on topic, has anyone made a plugin perhaps that allows the collision model stuff to be extracted/imported to/from a .obj file or at least raw data? i mean, i f we have the location of the verticie storage someone should be able to make HMT do something with it... I would but i dont have a clue how.

correct me if i'm wrong, but arent all posts in this sticky supposed to be questions or answers? not flames?

It did feel dirty, it is now clean. Pointless posts will be deleted. See Annoucment Flaming/Spamming for more info.

hey ang88, can u post ur plugin for making more seats in vhicles, it would help alot, and ty

i dont suppose that you would tell us what type of stuff it is cus there are a number of one thing like a number of shields. ok all im woundering is which one is the shield that is in hte lvl danger canyon in the middle

edit: i found glass to make bits come off it but how would u make glass that can actually break like make a bridge of it
