smooth

问题 I would like to know how to make a smooth jump in my game. Its a 2D game and the code is really simple but I would want to know how to make it better for it to slow down when it gets to the max height and then smooth drop. This is all I have for jumping: Player.y -= 50; 回答1: Your best bet would be to use a physics engine (Box2d etc). If you don't want the overhead of one though (if the only thing you'd use it for is jumping and not collisions) then you just need to add some friction to your

问题 I've searched and see lots of examples about this subject but I couldn't best way for me. I'm just a bit familiar with JS and jQuery and I want to ask about smooth scrolling. <a name="urunler"></a> <ul> <li><a href="#ppanjur" class="uruna">Plastik Panjur</a></li> <li><a href="#ipanjur" class="uruna">Alüminyum (İthal / Yalıtımlı) Panjur</a></li> <li><a href="#opanjur" class="uruna">Otomatik Panjur</a></li> </ul> I've a navigation like this. This scrolls instatly. But I want to do it slowly.

问题 Does anyone know why this very simple jquery animation works perfectly in some browsers like Chrome and seems to be bugged in Firefox 7.0.1? Here's a link to the animation. If you try it in Firefox you'll see that the animation sometimes freezes then restarts. As you can see the code is very simple, only one animation, no images, and inline CSS. html: <div id="content" style="position: relative;width: 500px;height: 500px;overflow: hidden;"> <ul id="slider" style="position: absolute;top:0;left

问题 i found this script to change images on hover. $(document).ready(function() { $('.rollover').hover(function() { swapImage(this); }, function() { swapImage(this); }); }); function swapImage(image) { var current = $(image).attr('src'); $(image).attr('src', $(image).attr('hover')); $(image).attr('hover', current); } But now i'm having the problem, that i want a smooth/soft transit and not that, what it does now. Here you can find a fiddle: JSfiddle Thanks and a nice sunday! 回答1: It is swapping

问题 How can I check browser smooth scrolling support via Javascript? Or how can I disable smooth support scrolling and enable fixed scrolling (without disabling scrolling in divs with overflow:auto and textarea)? 来源： https://stackoverflow.com/questions/9991668/how-can-i-check-browser-smooth-scrolling-support-via-javascript

问题 I would like to simulate "gravity" for one sprite. I defined a CGPoint which holds the gravity values. And I have tick method. //in my init I defined this: gravity = ccp(0.0f, -1.0f); -(void)tick:(ccTime) dt { if (enableGravity_) { //simulate gravity velocity_.x += gravity_.x; velocity_.y += gravity_.y; self.position = CGPointMake(position_.x + velocity_.x, position_.y + velocity_.y); } if (isAcceleratingEnabled_) { //I move my sprite here float angle = self.rotation; float vx = cos(angle * M

问题 I have some data which when plotted looks like the one shown in left on the picture attached. It has some kinks which I wish to delete and smooth-en to get a nice curve [shown on right]. Presently I manually delete the kinks and interpolate the deleted part by polynomial of high order [say 9]. Then I repopulate the deleted fragment and re-draw the curve. This takes a long time and I have quite a number of files to process. Could you folks suggest an efficient way to do this ? [in MATLAB or

问题 Im trying to smooth a graph line out but since the x-axis values are dates im having great trouble doing this. Say we have a dataframe as follows import matplotlib.pyplot as plt import numpy as np import pandas as pd %matplotlib inline startDate = '2015-05-15' endDate = '2015-12-5' index = pd.date_range(startDate, endDate) data = np.random.normal(0, 1, size=len(index)) cols = ['value'] df = pd.DataFrame(data, index=index, columns=cols) Then we plot the data fig, axs = plt.subplots(1,1,

问题 I'm measuring some system performance data to store it in a database. From those data points I'm drawing line graphs over time. In their nature, those data points are a bit noisy, ie. every single point deviates at least a bit from the local mean value. When drawing the line graph straight from one point to the next, it produces jagged graphs. At a large time scale like > 10 data points per pixel, this noise is compressed into a wide jagged line area that is, say, 20px high instead of 1px as
