Porting my mod (Does Forge have what it needs?)

[Dayanto]

Hello! I'm thinking of porting my mod to Forge but in order to do that, I first need to know if it's possible in the first place. I've done a bit of research and some digging in the JavaDoc but I haven't found the specific things I'm looking for, so I thought it would be better to ask someone with a bit of experience with Forge instead.

 

To give you a bit of background: The mod I'm developing is called PanoramaKit and it is used to create backgrounds for the main menu as well as - you guessed it - panoramas. It does this by rotating the player and capturing a series of images that together make up everything that is around you. (360 x 180 degrees)

 

There are mainly three things that I need for my mod to work properly.

 

* A hook that runs once every frame. This is necessary for the rendering.

 

* Preventing the player from moving the view (while the mod is capturing images).

 

* The ability to offset the camera from the player.

  Reveal hidden contents

 

There is a slight camera offset caused by the following lines of code which is a bit of a trouble.

...
487 else
488 {
489     GL11.glTranslatef(0.0F, 0.0F, -0.1F);
490 }
...

 

This means that the player actually always walks around slightly like in 3rd person mode. Now this doesn't matter at all while you're playing but it causes the images not to fit together. In my mod currently, I don't want to break compatibility with mods that are using the EntityRenderer class, I use an approach where I correct the offset by moving the camera at a later time (via a special hook).

 

// Undo player rotation
GL11.glRotatef(-player.rotationYaw, 0, 1, 0);
GL11.glRotatef(-player.rotationPitch, 1, 0, 0);

// Correct camera position
GL11.glTranslatef(0.0F, 0.0F, 0.1F);

// Redo player rotation
GL11.glRotatef(player.rotationYaw, 0, 1, 0);
GL11.glRotatef(player.rotationPitch, 1, 0, 0);

 

Most likely, the approach with Forge would be similar, but Forge doesn't have to think about compatibility as much, so perhaps there is a better way of controlling the camera already built in? (I don't expect to find any hook similar to the one I'm currently using, so this would probably be my only hope)

 

 

 

(*) As a last thing, if there is a way to roll the camera, that would also be good to know but it's not essential for the mod.

i know there is a hook but i dont remember the name, do some search (if u dont find, u can always use asm).

Ok, I'll keep looking. (Is this what you mean by asm?)

 

Out of the three, I was pretty much expecting the hook to exist. (I had to know for sure though) The other two however are my main concern. If you happen to know anything about them, it would help a lot.

 

Edit: I rewrote the original post a bit to make it clearer.

For the first issue, you can use the ITickHandler (or the IScheduledTickHandler). Just set its TickType to TickType.RENDER and register it on the Client-side!

 

Here's a tutorial on how to create one:

Sounds great! Thanks to both of you for the help!
