From here out, we will refer to client-side prediction as CSP. During your development you may also hear the term 'server authoritative movement'. CSP is a form of server authoritative movement, but they are not the same. As mentioned CSP allows the client to move in real-time while also ensuring they cannot cheat. Some server authoritative movements will ensure the client cannot cheat but does so by moving on the server only and relaying the results to clients. While both work, the latter of moving on the server and then relaying will result in the client to have a delay based on their latency. Having such a delay would be unfair to those with higher latency and could ruin the experience for players if your game is expected to have responsive movement. This is why having CSP built into Fish-Networking is so great! --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://fish-networking.gitbook.io/docs/guides/features/prediction/what-is-client-side-prediction.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
