Laravel search for the close results - laravel

Question

My app has an option to battle another player.
In order to match a player with another, I created a database field named score in my users table.
My goal is to match user with a another random user who is already SEARCHING for a battle. Both of the users has to be on +-100 score difference.
For example, user with score of 100 can battle players with score of 0-200.
I'm trying to search for all of the available options, but couldn't get how to do this.
Currently, I just output the first one in SEARCHING mode.
$pvp = PvpBattle::where('mode','=','SEARCHING')
->first();
How I can get all PvpBattle objects where the associated player1_id has +- 100 score difference from $this->me->score?

Answer 1

Try This code
WhereHas('users') is the user relation between PvpBattle and user
$minScore = $this->me->score - 100;
$maxScore = $this->me->score + 100;
$pvp = PvpBattle::where('mode','=','SEARCHING')
->WhereHas('users', function ($query) use ($minScore, $maxScore){
$query->Where(function ($subQuery) use ($minScore, $maxScore){
$subQuery->orWhere('score', '<=', $maxScore)
->orWhere('score', '>=', $minScore);
});
})
->first();

Answer 2

First find the score of player one to $scoreA or use $this->me->score
Then
$opp_list=PvpBattle::where('mode','=','SEARCHING')->Where(function($query)
{
$query->where('score', '>=', $scoreA -100)
->orwhere('score', '<=', $scoreA+100);
})
->get();
This gets all the players in mode searching with condition score +-100. first() returns the first result from the table.
How are you going to handle two requests at the same time pointing to the same user?
User A should be not returned as a result.
Add ->where('user_id', '!=', $user_id) to query

Answer 3

Use a join with the users table to filter the result by the score of the related user.
$pvps = PvpBattle::join('users', 'users.id', '=', 'pvpbattle.user_id')
->where('pvpbattle.mode','=','SEARCHING')
->where('users.score', '>=', $this->me->score - 100)
->where('users.score', '<=', $this->me->score + 100)
->get()
;
