Body
The <code>love.load</code> function runs only once. As you mention, it's generally used to set up data structures and pre-load other resources. You can use it to handle both the world pre-load and the menu pre-load. Then, control what is active via some sort of state. A simplified example: <pre><code>local state = "menu" function love.load() preLoadMenu() preLoadWorld() end function love.update(dt) if state == "menu" then updateMenu() else updateWorld() end end function love.draw() if state == "menu" then drawMenu() else drawWorld() end end function love.mousepressed(x, y, button) if startClicked(x,y,button) then state = "world" end end </code></pre> It's conceivable that you won't want to pre-load absolutely everything for your game on load. Maybe your game is just too big. If that's the case, consider working with an active scene. A scene might be the menu or maybe it's a game level. Again, a simplified example: <pre><code>local currentScene function love.load() currentScene = loadMenu() end function love.update(dt) currentScene.update(dt) end function love.draw() currentScene.draw() end function love.mousepressed(x, y, button) if startClicked(x,y,button) then currentScene = loadWorld() end end </code></pre> This second option is much more flexible in the long run. It can handle any number and type of scenes without conditional logic for each. It will require a little "object" thinking. All scenes need a consistent way to update and draw. If your world takes a while to load, you may want to display a temporary "world is loading" scene so your users don't get impatient.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
