Just to play with 3D (4.60 beta 2)

Comtois · Post by **Comtois** » Wed Apr 13, 2011 4:16 pm

Just copy this code in IDE and run it. I like The CreateCube, CreateSphere, CreateCylinder, now it is possible to create small demo for forum without medias.

Use cursor and mouse.

Code: Select all

This is fantastic!

Is it possible to make smoother lights though? I tried WorldShadows(#PB_Shadow_Additive) but the shadows still don't look smooth.
Also would it be possible to make the tank collide with the boxes as well?

(Don't know anything about 3D

Kelebrindae · Post by **Kelebrindae** » Thu Apr 14, 2011 10:34 am

@Comtois: Thanks for the link!

Cool demo, but I think you should reduce the size of your entities: it would make the physics look more "real".
I'd say the physic engine is calibrated to something like "1 unit = 1 meter in the real world".
In your demo, it means that every cube in the pyramid are 20 meters wide; when they fall, it looks like they move in low gravity; just like a real building appears to fall slower than a "Jenga" tower

...
I don't know if my explanation is clear, but the fact is: small entities fall quicker.

Take a look at this demo (press space to swing the hammer). The cubes in the pyramids are only 1 unit wide => their fall looks more realistic (in my opinion).

Nice demo

I tested WorldGravity (-1000) without success, and I see that you just made a bug report, thank you:)

I already tried adding EntityPhysicBody (0, # PB_Entity_BoxBody, 47), but without success. I do not know if it's a bug or not?
So to remedy this I added 2 entity. it works a little, and after a moment, it bug (no more collision).

Code: Select all

 RotateEntity(10, NodePitch(0), NodeYaw(0), NodeRoll(0),RotationAbs)
 EntityLocate(10, EntityX(0), EntityY(0), EntityZ(0))
 EntityLocate(11, NodeX(1), NodeY(1), NodeZ(1))

I have edited the code.

Since version 4.60 RC2, this code has a different behavior.

Place InitEngine3D() before InitSprite()
replace CreatePlane(1,2,2,20,20,1,1) by CreatePlane(1,30,20,20,20,1,1)

If you want the same Size as before -> Replace CreatePlane(1,2,2,20,20,1,1) by CreatePlane(1,40,40,20,20,1,1)

TileSizeX, TileSizeZ are replaced by PlaneSizeX and PlaneSizeZ

Post by **Polo** » Wed Oct 19, 2011 10:51 pm

On the Mac, with Comtois' demo I can only see a black screen, nothing more (not crashing, though).

With Kele's demo I can see some objects, though most of them seems to fall, I guess it's not the desired behaviour

BTW Kele's code is wrong at least on the mac, it requires to put init engine before init sprite.

@Polo:
Yes, the parameters for "CreatePlane" have changed in RC2 (and are better that way, methinks) along a few other things. I've updated my code (in the post above).
And now, it's possible to reposition the ball on the tee by pressing "R".

Hi Kelebrindae
regarding your hammer and ball example, i can't make it to work in 5.11 the hammer falls on the ground from the beginning, may be the problem with pointjoint and hingejoint, it works in 4.61, the example should be in the PB official examples.
