QUESTION
I am currently trying to learn Kotlin with the help of the book "Kotlin Programming The Big Nerd Ranch Guide" and so far everything worked. But now I am struggling with the "lazy" initialization which throws a NullPointerException which says
Cannot invoke "kotlin.Lazy.getValue()" because "< local1>" is null
The corresponding lines are:
...ANSWER
Answered 2021-Jun-08 at 16:39When something like this happens, it's usually due to bad ordering of initialization.
The initialization of the Player
class goes this way:
- the
name
property has its backing field initialized with the_name
value - the
init
block is run, and tries to accessname
- the getter of
name
tries to read thehometown
property, but fails becausehometown
is still not initialized - ...if things had gone right, the
hometown
property would be initialized now with the lazy delegate
So basically you're trying to access hometown
before the lazy delegate is configured.
If you move hometown
's declaration above the init
block, you should be fine.
You can see the fix in action on the playground

I am using a multi-file setup so I have both ui.r and server.r files. I am using the dataset below (small sample) which looks at UFO sightings in different states/provinces in U.S./Canada in 2016.
...ANSWER
Answered 2021-May-26 at 03:23I wrote your code to a single syntax but you can adapt it to ui/server form.
First, you don't have to write every single choice if this is available on the data. The selected
argument in checkboxGroupInput
can repeat the choices so that each one of them is selected on launch.
For the plot, you just have to add an extra filter for the Shape
column. Since this can be a multiple selection, the %in%
operator works for a vector of values.

I have a dictionary of abilityobjects that I'm trying to serialize in XML. Because you can't XML Serialize a dictionary, I change it into a list on serialization
...ANSWER
Answered 2021-May-17 at 18:44The way a lot of serializers work is by calling Add
on a list, only actually assigning anything back to the setter if the serializer created the list (perhaps because it was null
, or fixed size such as an array). So imagine the serializer doing:

I'm trying to use data that has an image url as part of an object. Normally, you would assign import the image and assign it to a variable. However, I am unable to do that as I'm planning on using an API call to get this image urls. Currently I'm using mock data and have been unable to successfully render the image.

QUESTION
I have a fireball that moves up and down but the problem is when its time to move down it has this snap to move back down and it doesn't look like the fireball is actually moving up and down smoothly at all. Is there a way I could make this better?
I want it to fall down like how a fireball would fall down instead of having that snap effect.
Here in my main loop I have the speed and the direction of how my bullets are moving.

Answered 2021-Jan-16 at 20:07Do you want to change the speed for just one platform, or change for all platforms?
If you want the same speed for all platforms, you should make speed
static.

QUESTION
These past month+ I learned many things by making a game in Unity.I have a lot of fun doing so. But some thing are still confusing me. I'm trying to setup a skill to the character and it goes almost well. When the character is casting the skill, the skill goes behind the character and not in front. So i thought to play with positions and rotations to make it work but still nothing. Worth to mention that the prefab has it's own motion. So my code so far is this. So help would be great and some teaching about the logic behind the skills system would be much appreciated. So take a look:
...ANSWER
Answered 2021-Jan-12 at 23:49Keep a reference to the character's transform and use that transform to instantiate the fireball instead of using the rotation from the hand. The rotation of the hand is not changing in relation to the body, so that's why the ball is always going in the same direction.
