Such mechanics would be perfect for testing the collision system, which I have yet to develop. So, now is time to make the game entertaining. I’m thinking of adding power-ups throughout the city which will make the car go faster. I also want the game to be played on the Apple TV.

Chunk tilemap physics The current implementation of TileMapLayer uses individual collision bodies for every single cell, which is extremely wasteful and a likely cause of runtime performance issues for 2D scenes relying on physics.

Collision detection. Your child just finished their coding class, and suddenly, theyre speaking a new language. They're energized, curious, and brimming with ideas. But then the school week picks up. Time gets tight. And little by little, the spark fades. At Real Programming 4 Kids (RP4K), coding doesnt stop when class ends.

I’ve tried changing the type (static/kinematic/animated) of the other objects, but collision detection still doesn’t work. The only time collision is detected is when I set the “Character” object’s Rigidbody2D type to “dynamic”. However, this causes the “Character” object to be affected by gravity, which I don’t want. normalize().multiplyScalar(this.speed);

Hi, i’m relatively new on Cocos Creator, but i hope i can help you because i’m working on collision from a while me too. At your node you need add two components, RigidBody2d (Kinematic, Static or Dynamic, depends on your needs) and a BoxCollider (Circle or whatever you need).

Go to Project Settings → Physics → Collision Matrix There, you can create groups and assign which group interact/ignore with which group. Then, in your node’s collider, assign the desired group for it. I’d suggest you to please read documentation and tutorials first and read them alot. Just my two cents and enjoy coding!

B grows and is now of size 2, and is still touching A - however, this won’t trigger a new collision event. I am aware I can just listen to the collision stay event, however that seems pretty inefficient as I only need to check again after the size changes… Is there any other, more efficient way to do that?
