collision-detection

Update: Found out that I was using the radius as the diameter, which was why the mtd was overcompensating. Another Update: The reason my balls are overlapping seem to be because there's only one check for every collision. After some research, some are saying that one of the ways you could prevent overlapping with objects piling up is to recursively perform the collision check. This works to an extent, and I suspect that it'd work even better if the physics were a lot more accurate. I'll update again if I find any more solutions. Also, I'm using Simucal's collision correction code. Hi,

I'm having issues during a minigame development using EaselJS with my collision detection system and I need someone's help. The issue occurs when the hero (a circle bitmap) collides an object and there's other object behind the first one, the hero collides with both objects, even if the second collision is blocked. Here's an image explanation: The cause of the problem is really simple, even if the problem itself isn't: This collision detection system is based on the future position of the circle (and not on its actual position), then if the next position of the circle intersect a rectangle, it

Is there any trick to determine if user clicks on given element rendered in canvas? For example I'm displaying rhombus from .png file with transparent background and i want to know if user click inside or outside that figure (like mouse-element collision). There is no concept of individual elements in a canvas - it is simply just an area that you're drawing pixels onto. SVG on the other hand is made up of elements which you can then bind events to. However there are a few approaches you can take to add click events to canvas: Position an html element that overlays the area on the canvas you

I'm making a game in which balls bounce around the inside of a much larger circle. The larger circle doesn't move. Here's the code that I'm currently using for these collisions: def collideCircle(circle, ball): """Check for collision between a ball and a circle""" dx = circle.x - ball.x dy = circle.y - ball.y distance = math.hypot(dx, dy) if distance >= circle.size + ball.size: # We don't need to change anything about the circle, just the ball tangent = math.atan2(dy, dx) ball.angle = 2 * tangent - ball.angle ball.speed *= elasticity + 0.251 angle = 0.5 * math.pi + tangent ball.x -= math.sin

I am trying to create a simple javascript game with simple physics. I can determine when 2 balls are colliding but I have having problems with handling the collision. Does anyone know of any useful tutorials on this? I've been searching the internet for a couple days but can't seem to find anything. In the UK, this would be A-level maths, so not too advanced. I think the phrase you need is " elastic collision ". That page has some of the formulae you need. Physics for JavaScript Games, Animation, and Simulations with HTML5 Canvas is a Book all about modeling Physics simulations in JavaScript.

I'm new to javascript, and trying to learn the collision detection for the paddle. This might be simple, but I don't know how to create collision detector of the paddle I created. How do this work and what do I have to put in order to create collision detection? (I don't need know about bricks, I just have to create simple animated/game javascript page.) Oh and do you know what kind of javascript am I using? because sometimes it is totally different coding so it's really hard to find my type of coding I can follow of.. Thankyou! var canvas = document.getElementById("myCanvas"); var ctx =

I have a Box2D world with a mixture of static and dynamic bodies. On collisions, I can only get the positions of the dynamic ones. Is it possible to get the positions of static objects? N.b., this is a development of a previous question, Box2D: How to get the position of a sensor? I found a way - in the collision, the center of the AABB will give the position contact.GetFixtureA().GetAABB().GetCenter() You can get the position vector using the following code: b2Transform t = body->GetTransform(); b2Vec2 pos = b2Vec2(t.p.x,t.p.y); 来源： https://stackoverflow.com/questions/5666834/box2d-how-to-get
