Hello everyone!

I am not sure if this is possible, and I haven't seen any game that has done this yet, but I want to try it.

I have read through TDK's multi player tutorial on the network. This sets up a game using the network commands on two separate computers connected either with a network cable or over a wireless network. However, I don't like the complexity in setting up a network game, I am more for the "plug and play" way. What I mean is I prefer the game to run on one computer with the screen split.

My laptop has a screen output, a blue plug at the back. You can connect any monitor or screen to it and the displayed graphics on my laptop can be seen on the monitor. Now, is it possible to display the 1st player's view on the laptop screen, and the 2nd player's view on the monitor?

I have no idea how this could work or if it is possible, but please give your advice!

what you want to do is create a bitmap, then type this after one players stuff is moved:



then move P2's stuff and do this:



and finally:



basically it turns out as what player 2 should see, only scaled down to half its height, on top of what player 1 should see, also scaled down. If you want P1 on top instead then switch the order of the two blocks of code. I made this from memory without DB running so dont be surprised if i overlooked something obvious

I think TheComet's talking about a dual monitor display.

Does the laptop display the same thing as the monitor when the monitor is plugged in, or does the monitor override the laptop's display and the laptop display's nothing?

If there is a display on both, you should be able to go to Settings > Control Panel > Display > Settings and setup the two monitors. There should be options to configure the display between the two - in which case you'd have to set up your game to match.

Enjoy your day.

It displays the same thing at once. I will try and set it up, thanks!

If they display the same thing at once, then no. That just means that the monitor is an alternate display, not a separate one. If you can set it up so that they're different, there might be a way. I know a game (Supreme Commander) that had some Dual-monitor stuff. I think DX8 or 9. If you get anything, then post it: I use two *different* monitors and would be glad to test.

OK, I managed to set it up so both monitors are my desktop, however, although I can drag my mouse and windows from one to the other, they are both separately drawn. So when I execute any DarkBasic program on the left one, it turns black and runs, but the right one still shows the Desktop. They are both different bitmaps being drawn.

How can I combine them both to execute together and share the same bitmap?

Yeah, exactly. They are combined already, but when I execute a DB program it only executes on one monitor and the other displays my desktop...

Am I understanding you by saying, half of the dbc window is displayed and working in one monitor and the other half is invisible? If you run DBC in windowed mode off the bat with a picture in it that covers the whole window, just dragging the window will tell you if it can be displayed in both monitors. To be thorough:

Try running DBC in windowed mode. DO NOT MAXIMIZE THE WINDOW. Use a small window that you can drag for the test. Drag the window from the primary monitor towards the secondary monitor. Does the dragging window split and spill over to the second monitor so that there is a portion on each monitor? If so, drag the sizing borders of the DBC window such that an equal portion is displayed on both monitors.

If this is working, once you have the window centered and dragged to size, hopefully in DBC you can split the camera view for each player at the center position of the DBC window between the 2 monitors. Avoid maximizing the window. If you maximize the window, it will only maximize on one monitor I think(which ever one you are currently working on). But test this. I could be completely wrong. I don't think FULL-SCREEN mode will work for a split view... I could be wrong about that too...

Let me know what happens.

Enjoy your day.
