There is a bug with collisions in my game

[selimanac]

This is not a bug. You shouldn’t use go.set_position in physics world. It mess the physics calculation. If you want to move your objects, you have to use ‘force’. (Use the force Luke)
And please use code fences when sharing a piece of your code. It is hard to read from a image.

Piercing collision object when gameobject move with fast speed!

You have to use ‘force’ if you want a stable solution on physics world. Your solution without a dt calculation is not appropriate and may acquire different speed on different hardware/refresh rate. Also using raycast is an other proper solution for tunneling.

Character In 3D Scene Is Having Collision Issues - Keeps falling for 1 frame

I think you misunderstood it a bit. go.set works fine with collision objects. It does however mess with the continuous collision detection (a.k.a “bullet”). For CCD to work, it needs to do continuous calculations, and that won’t work if you suddenly teleport the object to another place. As mentioned to you before, to make use of CCD, you need to only use forces to act upon the object. To help with your scenario though, there are (as mentioned) raycasts, and also shape casts. We haven’t implem…
