What's wrong with this? It's supposed to create 4 cameras with four different viewports. Annoying the heck out of me!

It gives me the first viewport and the rest of the screen blank.

And even if players=2 then it gives me 4 viewports

..should work..you set the width/height of the 2nd/3rd/4th cameras incorrectly.

I look over that about a hundred times and that was all it was... Thanks you, just took some eyes that haven't been looking over it a million times.

I'm sorry about this but... I'm having trouble getting the movement. The code's really messy

Using the method above to create the players, here's movement/weapon switching code:

p\cont$ is the controller for your player (mouse,keys,joy)
Part of this is your switching weapons and detonating them.

Here's the code to choose your control type: (AlphaGUI)

If AlphaGetReleased$()="1"
start=1
players_to_find$=AlphaGetValue$("players")
If players_to_find$="0" Then players=2
If players_to_find$="1" Then players=3
If players_to_find$="2" Then players=4
p1cont_find$=AlphaGetValue$("P1cont")
If p1cont_find$="0" Then p1cont$="Mouse"
If p1cont_find$="1" Then p1cont$="Keys"
If p1cont_find$="2" Then p1cont$="Joy"
If p1cont_find$="3" Then p1cont$="XboxJoy"
p2cont_find$=AlphaGetValue$("P2cont")
If p2cont_find$="0" Then p2cont$="Mouse"
If p2cont_find$="1" Then p2cont$="Keys"
If p2cont_find$="2" Then p2cont$="Joy"
If p2cont_find$="3" Then p2cont$="XboxJoy"
p3cont_find$=AlphaGetValue$("P3cont")
If p3cont_find$="0" Then p3cont$="Mouse"
If p3cont_find$="1" Then p3cont$="Keys"
If p3cont_find$="2" Then p3cont$="Joy"
If p3cont_find$="3" Then p3cont$="XboxJoy"
p4cont_find$=AlphaGetValue$("P4cont")
If p4cont_find$="0" Then p4cont$="Mouse"
If p4cont_find$="1" Then p4cont$="Keys"
If p4cont_find$="2" Then p4cont$="Joy"
If p4cont_find$="3" Then p4cont$="XboxJoy"
Cls
Print "Players: "+players
Print "P1: "+p1cont$
Print "P2: "+p2cont$
Print "P3: "+p3cont$
Print "P4: "+p4cont$
EndIf


Sorry it's so messy. It's a project I've restarted after a year gap. Had to convert the whole thing to types.

Hi Fuller - I had a brief look at the code and your movement with mouse and joystick will not work - this is why:


If MouseDown(1)
MoveEntity p\cam,0,0,move#
Else If MouseDown( 2 ) And MouseDown(1)
MoveEntity p\cam,0,0,-move#
EndIf 

;The program will never execute the code under 'if mousedown(2) and mousedown(1) because if mousedown(1) is true only the top bit will execute.  The same goes for your joystick movement code.


Something like this would work okay:


if mousedown(1)<>0 and mousedown(2)=0 then 

;move forwards

else if mousedown(1)=0 and mousedown(2)<>0 then 

;move backwards

endif

rats, I forgot to fix that. But none of the control methods work.
