private HttpProtocolBuilder httpProtocol= http
        .baseUrl("https://www.videogamedb.uk/api")
        .acceptHeader("application/json");

private ScenarioBuilder scn=scenario("My First Gatling Script")
        .exec(
                http("List all video games")
                        .get("/videogame")
              );

    setUp(scn.injectOpen(atOnceUsers(1)))
            .protocols(httpProtocol);
}
Pause:
We can use Pause command in between exec methods
Way 1:
.pause(5)
Way 2:
.pause(1,10)
Way 3:
import java.time.Duration;
.pause(Duration.ofMillis(5000));

How to check Response Status?
Way 1:
.check(status().is(200))
Way 2:
.check(status().in(200,201,202)))
Way 3:
.check(status().not(404),status().not(500)))

How to extract response and Assert using jsonpath?
https://goessner.net/articles/JsonPath/
https://gatling.io/docs/gatling/reference/current/core/check/#jsonpath

For Example: .check(jsonPath("$[?(@.id==1)].name").is("Resident Evil 4")))
How to extract response and Assert using jmespath?
https://jmespath.org/

Example:

if it is number

.check(jmesPath("[? id ==`1`].category").ofList().is(List.of("Shooter")))
if it string 
.check(jmesPath("[? category== 'Shooter'].name").ofList().is(List.of("Resident Evil 4","Doom")))
