[1.15.2] Isometric View

[quinn50]

So I am currently working on a Action RPG hack and slash mod for 1.15.2 and I have having trouble figuring out how to create an isometric view in 1.15.2. I have looked at other mods such as mineshot and shoulder surfing reloaded and I have figured out how to modify the position of the player camera using reflection (ActiveRenderInfo has some methods and fields with access modifiers protected and private. I have tried doing some openGL things but I couldn't figure that out. I also need to figure out how restrict the player from looking up and down. 

 

Code for my cameraSetup event handler

Spoiler

@SubscribeEvent(   priority = EventPriority.LOWEST,
            receiveCanceled = true)
    public void onCameraSetup(EntityViewRenderEvent.CameraSetup event){


        if(Minecraft.getInstance().gameSettings.thirdPersonView == 1){
            final ActiveRenderInfo info = event.getInfo();

            float prev = ObfuscationReflectionHelper.getPrivateValue(ActiveRenderInfo.class, info, "previousHeight");
            float height = ObfuscationReflectionHelper.getPrivateValue(ActiveRenderInfo.class, info, "height");

            double x = MathHelper.lerp(event.getRenderPartialTicks(), info.getRenderViewEntity().prevPosX, info.getRenderViewEntity().getPosX());
            double y = MathHelper.lerp(event.getRenderPartialTicks(), info.getRenderViewEntity().prevPosY, info.getRenderViewEntity().getPosY()) + MathHelper.lerp(event.getRenderPartialTicks(), prev, height);
            double z = MathHelper.lerp(event.getRenderPartialTicks(), info.getRenderViewEntity().prevPosZ, info.getRenderViewEntity().getPosZ());

            try{
                Method setPosition =  ObfuscationReflectionHelper.findMethod(ActiveRenderInfo.class, "setPosition", double.class, double.class, double.class);
                Method movePosition = ObfuscationReflectionHelper.findMethod(ActiveRenderInfo.class, "movePosition", double.class, double.class, double.class);
                Method setDirection = ObfuscationReflectionHelper.findMethod(ActiveRenderInfo.class, "setDirection", float.class, float.class);
                setPosition.invoke(info, x, y, z);


              //  setDirection.invoke(info, xRot + 180.0F, -328);
                movePosition.invoke(info, -10, 2, -1);

            }catch (Exception e){
                e.printStackTrace();
            }


        }



    }

Re the first part: I'm not sure what you're asking.

Re the second part: search the vanilla code for MouseHelper.updatePlayerLook() and have a poke around to see how you might override it.

Note that you also shouldn't look up methods via reflection every time the camera updates.

Look them up once, and store them in a static field.
