Confused about GL11.Rotatef ...


Frag

Recommended Posts

Hi guys,

 

I am rendering a simple fish ... no issue so far. But if I want him to jump in the air, over the water, I want to rotate it so it will jump face up (head pointing to the sky). I added this to the code and I see that the fish rotate, but it will never rotate the same way twice in a row. Sometime they will jump head first ...sometime they will jump tail first ...or simply side first. I am really confused. Someone could help me out?

 

protected void func_82430_a(EntitySalmon par1, float par2, float par3, float par4)

{

if (par1.worldObj.isAirBlock((int)par1.posX, (int)par1.posY, (int)par1.posZ))

{

    GL11.glRotatef(90F, 0.0F, 0.0F, 1.0F);

}

        GL11.glTranslatef(0.0F, (float)(-par1.GetRenderValueFromSize()), 0.0F);

        super.rotateCorpse((EntityLivingBase)par1, par2, par3, par6);

 

}

 

I tried other options like:

 

GL11.glRotatef(90F, 1.0F, 0.0F, 0.0F);

 

GL11.glRotatef(90F, 0.0F, 1.0F, 0.0F);

 

GL11.glRotatef(90F, 0.0F, 0.0F, 1.0F);

 

Nothing really works ...the fishes rotate, but never heads up.

 

Simply, I just want my fish to be rendered head pointing to the sky when its location is an air block. Someone can explain?

 

Thanks in advance...

That's because the GL11 axis are not always same in the method.

Just do it with your model animation...

 

Could you elaborate ... what do you mean by the GL11 are not always the same? Any examples?

I mean, that it would be "rotated" already.

Since GL11 rotation applies for current axis, the result is dependent on the axis.

Ok so what you are saying is that if ...lets say a fish jump twice  ... the first time it will rotate to 90 degrees ...and the second time it will rotate 90 more degrees? That would explain the random feel rotation I experience. It does make sense.

 

Can I use a call to reset the rotation? As you noticed I have a IF that detect if the fish is out of the water. So in the else part, I could reset the rotation.

 

Any call I could use? OpenGL is really new to me.

No, I does not mean that the rotation angle is variable.

the rotation angle is constant 90 degrees,

[bold]But the "Rotation axis" would be changed.[/bold]

and it is impossible to reset the rotation...

 

Your fish model would have setRotationAngles or something.

set the rotation angle your fish model there..

The rotation degrees are also in radians, not degrees.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

Whoops, I thought I had one in my code and I checked where I was getting my angle values from (and having radians) but didn't check to make sure I was actually using GL11 for the rotation.  You're right, it uses degrees.  The Techne model, however, does use radians.

    • Hello. I've been having a problem when launching minecraft forge. It just doesn't open the game, and leaves me with this "(exit code 1)" error. Both regular and optifine versions of minecraft launch just fine, tried both with 1.18.2 and 1.20.1. I can assure that my drivers are updated so that can't be it, and i've tried using Java 17, 18 and 21 to no avail. Even with no mods installed, the thing won't launch. I'll leave the log here, although it's in spanish: https://jmp.sh/s/FPqGBSi30fzKJDt2M1gc My specs are this: Ryzen 3 4100 || Radeon R9 280x || 16gb ram || Windows 10 I'd appreciate any help, thank you in advance.
    • Hey, Me and my friends decided to start up a Server with "a few" mods, the last few days everything went well we used all the items we wanted. Now our Game crashes the moment we touch a Lava Bucket inside our Inventory. It just instantly closes and gives me an "Alc Cleanup"  Crash screen (Using GDLauncher). I honestly dont have a clue how to resolve this error. If anyone could help id really appreciate it, I speak German and Englisch so you can choose whatever you speak more fluently. Thanks in Advance. Plus I dont know how to link my Crash Report help for that would be nice too whoops
    • I hosted a minecraft server and I modded it, and there is always an error on the console which closes the server. If someone knows how to repair it, it would be amazing. Thank you.
