[Casting Byte Ptr to Tvec3]

void _stdcall EntityCollisionCallback( TEntity entity0, TEntity entity1, byte* position, byte* normal, byte* force, flt speed )
{
TVec3 hitforce;
hitforce.X=force[0];
hitforce.Y=force[4];
hitforce.Z=force[8];
}

 

Ehm, you mean I should use C++ code in Blitzmax?

 

The most of the EntityCollisionCallback parameters seem to be pretty useless if I can't get them in an usable format for Blitzmax.

[Casting Byte Ptr to Tvec3]

I want to use the force parameter from Collisioncallback.

But it is passed as Byte Ptr. How do I get the force as Tvec3?

[Object looking messed up from below]

There are a few models I have to convert from a dexsoft pack to gmf.

They are ok, except if watching them from below. The same if I

create a plane disk and extrude it. Looks nice from all sides, except from below.

Is there a way to 'close' this objects?

[Loading a lot of textures]

Hello,

 

I have to load a lot of textures for my 2d animations.

At the moment they are a few hundred. Every frame as a single .dds file.

They are being preloaded at game start.

Is it better to use for every animation one big file instead of a lot small ones?

I'm thinking about something like vram fragmentation?

 

Do I have to be scared about overstuffing the vram?

[Simulating a shockwave with Newton]

don't know if i am following this correctly but couldn't you create a mesh at the size you want, then just get the AABB of the mesh using GetEntityAABB?

Yes, you are following correctly. Nice workaround.

Will add it to my function.

[Simulating a shockwave with Newton]

@Tyler

Yes, of course. Vec3s needed. But it throws the error

already at the create method "Compile Error: Identifier 'Create' not found".

@ VicToMeyeZR

Thats just because the forum uncourteous changed code to comments.

I had to add a ' at the end of every comment and forget that one.

[Simulating a shockwave with Newton]

Hello Tyler,

 

Could you possibly share how you did it?

 

I really wanted to do that, but I thought my solution is

not really good. That's why I wrote "sufficient".

Ok, here it is.

Code in Blitzmax:

 

Function ApplyShockwave(position:tvec3, intensity:Float)
Local body:TBody
For Local gameobject:TGameObject = EachIn TGameObject.list
	body = gameobject.body
	If body <>NULL
		' create a marker to make point of shockwave visible, replace with a pivot later '
		Local marker:TMesh = CreateCylinder(8)	 
		PositionEntity(marker, position)

		Local mpos:TVec3 = EntityPosition(marker)
		Local spos:TVec3 = EntityPosition(body)
		Local distance:Float = EntityDistance(marker, body)

		Local force:TVec3 = New TVec3
		' substract position vecs  and calculate force to apply'
		force.x = (spos.x - mpos.x) / distance
		force.y = (spos.y - mpos.y) / distance
		force.z = (spos.z - mpos.z) / distance

		If distance < 1 Then distance = 1 ' because of massive force if <1 '
		force.x = force.x / distance * intensity
		force.y = force.y / distance * intensity
		force.z = force.z / distance * intensity

		Local tforce:TVec3 = TFormVector(force, marker, Null) ' thanks Flexman! '
		If EntityDistance(TEntity(body), marker) < 10 ' shcokwave only affects bodies in this distance
			AddBodyForce(body, tforce)
		EndIf
	EndIf
Next

I am cycling through all my gameobjects because I couldn't figure out how to pass the two vec3s

to TAABB in Blitzmax at the moment.

Local t:TAABB = New TAABB.Create(Vec2(10, 10), Vec2(0, 0))

throws an error.

[Simulating a shockwave with Newton]

Thanks guys, got something sufficient working.

[Simulating a shockwave with Newton]

I have a ship and an exploding mine.

The mine shall create a shockwave which affects the ship.

Playing with AddBodyForceAtPoint() did not lead me in the right direction.

 

I could do a pointentity() from mine to ship and shoot an invisible body,

but I don't like the idea.

 

Inspirations, please.

[Batch Texture Converter]

I've switched to Windows 7 X64 in the meantime.

Fails althoug with "wating for threads". Most time a the sixth file.

Two cores only

Hopefully waiting for the update, fully trusting in kleptos skills.

[Alpha overlap issues...]

I had the same problem but do not remember exactly how I solved it.

Try depthmask=0.

[Shadow Rendering Error]

Thanks Josh.

 

I've tried multiple values but it seems like its not working.

 

If I use 10 for the first value, the shadow quality is perfect but the distance is very short. If I change it to 20, the distance increases but the quality drops.

 

What exactly do these numbers mean? As in what is the first number do and the second number and the third number?

 

I looked it up in the wiki but it only references the BlitzMax code version of it, not Lua/Ini or editor.

Try to change the stage parameter of Shadowdistance.

Do you do some scaling for your scene?

May be this thread helps:

[Batch Texture Converter]

I didn't use drag but "add folder" button. Nvidia dds tools only have a command line utility.

The directx sdk supports batch converting? Which version do I need?

[Batch Texture Converter]

Fails here on my PC , I just can batch convert 1-4 files.

Skips a few pics on my Laptop. From 32 only ~25 get converted.

The png files I'm talking about are produced with TimelineFX, I don't know

if they are incorrect.

[Newton: Elastic Balljoints?]

No, 2D with the option to switch to 3D later.

Yes, some similarity.

[Newton: Elastic Balljoints?]

I solved this by creating a second joint between the spheres

at a slight different position (0.05). Works fine now.

[Newton: Elastic Balljoints?]

My Balljoints seem to be elastic.

I'm not sure if I should use that as feature for my game or not..

If my hardworking ship has too much to carry this happens.

This are just a few spheres connected with Createballjoint().
