It is also more accurate since you have less rounding errors.

If a user finishes building a resource field, uses the market, builds a structure, etc you need to update the amount of resources (and the 'last update time'), because you cannot keep track on these kind of events simply.īy calculating the resources the database load is reduced, since you do not need to write the new values every time when the user refreshes the browser page. You might to consider caching all resource amounts somehow, since these values are required a lot, improving the communication with your database. You could also the let browser script calculate these amounts. If you read the resource values (for a page refresh or something), you need to add the amount of resources gained since the 'last update time' (depending on the amount of resources fields and boni the user gets) and send that value to the browser. A cronjob/scheduled task would work well to make sure everyone is updated, but in some situations, it might be better to simply measure how long it's been since you've updated each user's resources, and then update them on every page load they make while logged in by multiplying the time they've been away by the rate at which they gain resources - that way, you avoid updating until you actually need the new value.įor a Travian like resource management you need to keep track when you updated the users resources for the last time. If it varies how quickly people can get resources, you'll need to update the data periodically. That's going to be a bit of a problem if the rate can ever change, though, so if you use this solution, you're pretty much stuck with the rate you pick unless you rewrite the handling entirely (for example to the one below). The correct answer depends on your exact needs.ĭoes everyone always get resources at the same rate? If so, a simple solution is to track how long their user has existed, calculate the amount of resources based on the rate they're getting, and subtract the number of resources they've spent in total.
