    GL_INVALID_OPERATION in Setbuffer(gbuffer)

    well offhand i don't see how what you posted for the plane has anything to do with the drawtext? Nor do I see any issues with the drawtext other than the fact that you are basically drawing them on top of each other and over the top of the Stats... I placed both snippets in a program and have not had any issues

    Think I did not make it clear enough. The plane creating and deleting code only fails if I use some drawtext() in my code.

    Else my projects runs perfectly.

    But I see, there is no way then stripping down my project to make an working example.

    This error is thrown In renderer.bmx (using framework),if I

     

    - create a plane (or cube or sphere) and remove(!) it a bit later

    - ONLY if the plane is in view of the camera

    - AND if I use some Drawtext(), and then more then once (one line alone is not enough)

    - and not always, just 75 percent.

     

     

    Code used to crate the plane:

    		Global plane:tmesh = createplane()
		If KeyDown(KEY_ENTER)
			DebugLog("plane removed and new created")
			FreeEntity(Plane)
			Plane = CreatePlane()
		End If

     

    Adding this code alone does not produce the crash, but..

    		Local Vec:TVec3 = Vec3(10, 10, 10)
		Local text:String = "camera"
		DrawText(text + vec.x + vec.z, 100, 10)
		DrawText(text + vec.x + vec.z, 10, 10) 
		DrawText(text + vec.x, 100, 10) 
		DrawText(text + vec.x, 100, 10)

     

    .. if I activate fw.setstats(2) too, it crashes!

     

    Sorry, no working example code yet, will do it if there are no ideas.

    It took me three days to get near this little ******* of an error.

    Trying to run my project on the laptop (2.26 worked well), I get an shader compile error.

    Using latest official drivers from Dell.

     

    Does this mean my laptop can't run LE 2.3?

    Framework ? not Framewerk?

    Can I use the mod or not? I can't follow this.

    If i create a sinple file with

    framework leadwerks.engine
import leadwerks.framewerk

    there is this compile error:

    Hello,

     

    I'm just trying to move my project from 2.26 to 2.3.

    There will be a few questions I'll have.

    The first one (Blitzmax specific).

    Compile error if I include leadwerks.framewerk:

    My findings are, from my testing tonight, that using the torusforphygen.obj file with the 2.26 tools obj2gmf.exe and obj2phy.exe does produce a working dynamic physics mesh exactly like the one posted by MG (torus with green physics mesh) when placed in the 2.26 Sandbox.

    Can you mail me your .gmf and .phy file, please?

    volker [at] skopia.de

    I'm waiting for my 2.3 upgrade (hint: paypal, Josh) to continue testing.

    I really appreciate all the helping. Most features are finished for my little game

    and I could start leveldesign.

    There is no problem with making concave physically active objects. A concave object must be made out of multiple convex ones.

     

    I looked at your .obj file and it is a single object. Break it up into multiple convex pieces, within one file, and it will work perfectly.

     

    Which .obj file do you mean? The torusforphygen.obj, the simple.rar or simpleac.rar?

    Just to clarify you are using the ConvertMesh.exe to generate the .gmf's? .. I am simply dragging the .obj onto the obj2gmf.exe in the 2.26 tools folder.

    Yes, used Convertmesh.exe for .gmf. But this should not affect the . phy file.

    Didn't know that dragging works. Used the commandline all the time.

    I repeated the process using the supplied .obj to generate both the .gmf and .phy using the tools in my backup 2.26 SDK, 2.26 as requested, as volker is not using 2.3 tools. The result is still as per pic I posted.

     

    Using the 2.3 tools in the Current SDK the result is as per pic you posted above.

     

    Using AC3D to generate a range of shapes exported to .obj I can't reproduce the error no matter which method. Maybe its an issue with Milkshapes .obj exporter? I don't have milkshape so cant test that. :blink:

    I did the same process I did in Milkshape in AC3D to test if it is a Milkshape problem.

    (Model created in AC3D -> obj -> Convertmesh and Obj2Phy)

     

    Same result. ;)

    Using the obj2phy.exe from the 2.26 SDK and your included .obj .. then using that .phy file with your included .gmf dragged into the 2.3 editor

    This is getting crazy.

    I installed a fresh LE 2.26 on a clean virtual pc, to be sure not to mix files; copied only the

    test89.obj to it and converted it with obj2phy. I get a phy file like in my screenshot.

     

    Just ordered 2.3 to get behind this mystery.

    Back again. Did some more tests.

    Looks like I'm unable to convert even a simple object to a usable convex hull.

    Will be a funny game; with all complex objects static :blink:

     

    Here is a simple object made in Milkshape and converted with obj2phy:

    http://www.skopia.de/forum/simple.rar

    And this how it looks like:

    http://www.skopia.de/forum/simplephy.JPG

    Can anyone convert this succesfull (preferred with the tools from 2.26)?

     

    Let's not talk about complexer models:

    Also just as an informational point, if you do decide to update from 2.26 to 2.28 ... you will have to redo all your .phy files again, see HERE

    Good to know. But I'll stay at 2.26 if possible to get my project finished. Then I will go to 2.3 (2.4 :) ).

    I do the mass settings directly in code, so I wondered why I should use an ini file..

    Tried ob2gmf and then phygen too.

     

    As I said, I modelled a simple torus in Milkshape and the phy file although gets screwed up.

    http://skopia.de/torusforphygen.obj

     

    Looks like phygen doesn't work with this kind of objects.

    Thanks for your time guys.

    Do you mean the .phy file created with obj2phy? Did you create an .ini file for the model?

    Ehm, no. I converted the obj to gmf with meshconvert.exe (which creates no phy file).

    Then dragged the gmf in sandbox (which then automatically creates a phy file).

    Then deleted the phy file again. Used Loadmodel to load the gmf in sourcecode (which creates a phy file).

    Both times the phy files look again like in my screenshot.

     

    No, what should be in the ini file?

    Hi,

     

    I'm pretty disappointed which convexhull phygen created

    for my model. The object must be dynamic, so I cant' use collisiontree.

    No way to fly through this gate :P

    I modelled a simple torus of the same size and created a .phy for it. Doesn't help.

    Any workarounds for this?

    Removing body automatically removes mesh

    in Programming

    Posted

    The funny things is, that this only happens when called out of the Collisioncallback function, else not.

    For testing I've set a field "destroyme" to true out of the callback function and then

    removed the object from the update method. Works perfect.

     

    And of course I did a NULL test for the mesh. Mesh was not NULL.

    Tried to remove the mesh only if Entityexist(mesh)=true. Fails too.

     

    There is a lot of trouble with Collisioncallbacks for me at the moment.

    For ex. I can cast an entity1 to a body, but getbodyveloctiy() then crashes the engine.

    Did a NULL test too.

     

    There must be going on something beyond the curtain. :blink:

    Removing body automatically removes mesh

    in Programming

    Posted

    Hello,

     

    I'm removing an object out of a collisioncallback function.

    Therefore a body and a mesh must be freed (the mesh is parented to the body).

    If I call the remove method normally the body is freed and the mesh is freed; works fine.

    If I call it out of the collisioncallback function, the Freeentity(body) does

    magically removes the mesh too, so I get an error at Freeentity(mesh).

    Is there an explanation for this behaviour?

     

    Function MineCollided(entity0:TEntity, entity1:TEntity, Position:Byte Ptr, Normal:Byte Ptr, force:Byte Ptr, speed:Float)
If TMineTracer(entity0.userdata) <> Null
	 TMineTracer(entity0.userdata).remove()
End If
End Function

     

    Type TMineTracer
Method Remove()
	FreeEntity(Self.body)
	FreeEntity(Self.mesh)  ' throws an error, BUT only if called from MineCollided() '
	link.Remove()
End Method
end type
