Roadposts and Milestones?

[Granger]

Should be a server feature.

I long for a client that can show a line between the last road spot and the next one being indicated.

has it been suggested in one of the client threads?

Should be a server feature.

Like server has nothing to do right now and easily can run additional path calculations and sending the results to client on your every mouse move? Jeez...

Preview feature of convenience nature, has to be run on the client. Anyone thinking otherwise should not be allowed to any code vicinity.

Because

Code: Select all

send.line(pointA, pointB)

is highly computational work, right?

Server doesn't have to compute any of it, just tell the client to draw a line from A to B. How basic or fancy the graphics are is up to the client.

It's both server and client. Server has to send starting coordinates (derived from turning point of the milestone on which "extend" or "connect" has been clicked). That's two long integers (only). Client has to draw the line and server does not need to know where mouse hovers currently.

Didn't we talk about PREVIEW of the line between control points of the road before next post is put down? That mean the line changes literally every time you move your mouse to new grid cell.

My point is - there is absolutely nothing to gain here by moving the computation which is not affecting anything apart user convenience (therefore nothing to protect against client-side hacks) from client to server.

The client requests the specific coordinates of the last post in the chain. The server sends it. The client tracks the line between the last post and where the next post goes. It's not a difficult operation if this is done client or server side, and doesn't incur much more bandwidth or processing time over what was previously done.
