Glad to hear that. Tomorrow morning I will test your code on third machine(much better performance) and see if the animation is smooth. Ty again.

I cannot migrate to the latest version, because not all of the required mods currently support newer versions.

Already moving to 1.10.

Of course, nothing changed except the speed. Rewatch the second video. I am having lower FPS there (100+ players nearby) and animations are damn smooth. I cannot achieve that.

On the first, weak machine around 20 frames. On another around 70. Both have the same issue. And I can notice why. PartialTicks are unequal, so that xOffset is unstable, which causes jumping animation.

Of course no. Compare both animations. Mine is laggy, not smooth. And the other one is so smooth. No lagging at all.

P.S.S In my version I have disabled restrictions on movement, so you can easily notice lagging animation.

Captured two videos for you. First one is mine, second one shows desired version. P.S. Look only on the top left corner, it contains "notification". https://www.dropbox.com/s/kuh50e4tvnqn1kg/my notif.mp4?dl=0 https://www.dropbox.com/s/xle16vgqqjvz4kn/desired one.mp4?dl=0

I will post a video as soon as possible.

Ok. Imagine drawing a rectangle with built-in drawRect function from Gui class. I am trying to move it SMOOTHLY across the screen. To be more simple: have you ever seen Windows 10 Notifications, that appear from the right bottom side of the screen? Thats what I am trying to recreate. Now it is moving "unstable", not smooth. Maybe I need to change incrementation of current value to much smaller value, but if I will do that - the speed of animation will be VEEERY slow. Reminding Windows 10 notification. Fast and smooth. Offset? That is a number which represents how far will the rectangle move on the next frame.

Did everything you wrote: I am updating current every tick and rendering every frame. I logged the offset to the console and noticed that offset is not equal. I mean this: Here is an updated code: Every RenderGameOverlayEvent.Post: float actualValue = this.lastTick + (this.current - this.lastTick) * partialTicks; this.currentNotification.draw(actualValue); ClientTickEvent: @SubscribeEvent public void onClientTick(TickEvent.ClientTickEvent event) { if (event.phase != TickEvent.Phase.END) return; NotificationsMod.NMANAGER.updateCurrent(); } updateCurrent method: public void updateCurrent() { if (this.currentNotification == null) return; this.lastTick = this.current; this.current += 2F; // Bigger number - faster animation } Even if I do this.current++; animation/offset are not "pretty". Is that normal? Or am I stupid?

OK, I am a bit closer. You said How can I get every tick? As far as I know RenderGameOverlayEvent is called every FRAME, right? So how can I manage to get every TICK?

Am I on the right way?: private float current = 1, lastTick = 1; // "1" is wrong, cause it will lead to 0. It is obvious. /*....*/ this.lastTick = this.current; this.current = this.lerp(partialTicks); this.currentNotification.draw(this.current); /*....*/ private float lerp(float partialTicks) { return this.lastTick + (this.current - this.lastTick) * partialTicks; }

@diesieben07, I got the logic, but imagine that current and lastTick get 0, so that accordingly to the formula actual = 0 + (0 - 0) * 0.xxxxx always equals zero. So current value will be 0. Next time it will repeat, again and again.

Wait wait, I think I got it. I need to test it!

Ok, I got it, but here is the thing: when I am starting to draw, there is no last tick, cause it only started to draw, I believe you can understand me. What shell I do?

Good day. I need help with making a smooth animation. But first some entry information. I am trying to smoothly move rectangle from left to right. A pretty simple task I thought: use RenderGameOverlayEvent and redraw rectangle every tick. But animation looks pretty ugly, not smooth at all. I did research for 2 days and found something called "partialTicks". @diesieben07 wrote that this can be used to create smooth animations. But I ran into a problem. Here is a formula that @diesieben07 has mentioned: What's the problem? Maybe I do not understand something, but as I can see "actualValue" will always be 0 because the initial value is 0F and there is no next value. It is hard to explain, but I want to apply my code with comments. NOTE: I have already registered my events in the main class. Private Gist link: GitHub Gist URL
