[1.11.2] Gui drawScreen not with FPS


SuperHB
 Share

Recommended Posts

I'm currently working on a mod that adds arcade machines into minecraft. I currently have the gui to render based on ticks. This isn't the best as depending on the FPS the game could run too fast or too slow. I was wondering if it is possible to render parts in GuiScreen#drawScreen consistently at different FPS?

Could you please elaborate on that? You can't render anything as a tick happens as rending must happen each frame due to buffers being cleared. A tick is a semi-constant 1/20th of a second. A frame is any numerical value depending on a magnitude of factors.

Considering above, there is a way to render based on ticks, and it is used by Vanilla entities, chests, etc... Very often in the render/draw method, you get a float parameter partialTick. It is between 0 and 1 and it represents how much in-between 2 ticks the current frame is. Use it to interpolate between previous and next tick and you get smooth transitions / animations.

This is still rendering every frame. You are animating every tick. This is really the only way to do this properly.

The updateScreen method in GuiScreen is called once per tick and can be overridden in your custom GUI.

If you were to make a spinning wheel, for example, you would update the rotation of the wheel every tick in the updateScreen method and then make the wheel spin look smoother in the drawScreen method by using partialTicks.

catch(Exception e)

{

 

}

Yay, Pokémon exception handling, gotta catch 'em all (and then do nothing with 'em).

I have a tick counter variable and when that reaches a certain number, the code inside the if statement will run. The problem with this is that the speed of the animation now changes depending on FPS.

Lets say that every 20 ticks I have the code run. In game, if I get 20 FPS the animation will be slow, but if I have 200 FPS the animation will speed up. I'm wondering how I can stop it from doing this, to keep a consistent speed when the game is running at different FPS.

As @Earthcomputer said GuiScreen::updateScreen gets called each tick so operate on your timer there. You still have to render each frame obviously.

This is my first time working with partialTicks. I'm guessing I have to use this formula?

partialTick + partialTick * (currentTick - previousTick)

I have the previousTick and currentTick updated in updateScreen like so:

@Override
public void updateScreen () {
    previousTick = currentTick;
    currentTick++;
}

But I'm not really sure what to do in drawScreen to make sure it runs the animation consistently

partialTicks is the amount of a single tick that had passed. Using it depends on the way your animation is done. For example if you have a wheel a rotation of which equals to the amount of ticks the GUI is open you would get it's rotation angledeg like this:

ticksExisted + partialTicks.

You don't need to store a previousTick in this case as previousTick always equals currentTick - 1.
