QUESTION
Currently im using the Position of two objects (comets and the ship) to detect if they collide.
...ANSWER
Answered 2021-Mar-11 at 00:26Bevy doesn't have a complete collision system currently. Unless it has been expanded in the few months since the introductory page was created:
PhysicsMany games require collision detection and physics. I'm planning on building a plug-able physics interface with
nphysics
/ncollide
as the first backend.
Fortunately, this simple example is actually provided by bevy::sprite::collide_aabb::collide
which does simple AABB collision detection.
QUESTION
I'm making a space invaders type game and wanted to ask how i can make it so that the bullet in the following code doesn't follow the spaceship once its shot.
...ANSWER
Answered 2020-Nov-16 at 18:26You just need to set bulletX = characterX + 20
once - when the bullet is fired. Currently you set it to that with each while run
loop iteration, which is why its position is getting updated constantly. So, if you removed that, and updated the X position only when needed, this is how that part of your code could look:
QUESTION
I am having an issue with rendering code blocks in a documentation project using Mkdocs with readthedocs theme. Code blocks seem to not parse correctly new lines, so all code in a code block is rendered as a single line.
The repo can be used to reproduce the example, https://github.com/segrelab/comets-manual. The rendering can be seen in https://segrelab.github.io/comets-manual/.
The only hint I have found on google is this but it doesn't seem to be providing any solution, beyond identifying that the problem is related to css (indeed, I ave tried other themes and the code blocks render correctly).
Does anybody have an idea of how to solve this?
...ANSWER
Answered 2020-Aug-10 at 02:12First of all, please make sure that your tool is up to date (I can't reproduce the wrong rendering of the code blocks):

QUESTION
I began developing a "Spaceship vs Comets" style game last week and now I have come to a stop.
The purpose of the game is to shoot the comets before they pass your ship. You make the comets explode by firing at them. Simple idea!
However, sometimes when I play I get the "IndexOutOfBounds" error. It almost always appears when I haven't fired for a while (The size of my shots ArrayList is 0) and when I then fire and it collides it crashes.
So I have some kind of error in my code, but I really can't see it. I now hope that one of you might see why this accurs and save me from further "IndexOutOfBounds" errors! :)
Here is the part of the code that fails, including the functions that I use to move the comets and shots:

...ANSWER
Answered 2020-Mar-13 at 14:42Try to adjust here if(!comet.getComets().isEmpty() && !comet.getComets().isEmpty())
. You are checking for comet array twice.
Let me know if it works.
