Beginner problem with DelayTimer

[jrmorgan56]

Quick question:

I have a text game and I would like to control the speed of the delay between prints with 3 buttons (Slow, normal, and fast). However, I don't know how to get the game to see the user CHANGE the speed in the MIDDLE of the game. It stays with whatever was initially selected.

I know you can't fix my problem specifically without seeing my code, but if you wanted to setup something similar, what technique/plan would you use?

try using GetTickCount and set e varialbe to the speed set

Or a timer or what ever...

it depends how you fix the delay of the game in first place.
It#s probably something like:

if TimeNow>TimeOld+xxx then
  'continue
Else
  'wait till next timeloop
end if

if you have a value for xxx change it to a variable. And it case the use clicks on one of your speedcommands change the variable

i usaly do it like this:

Dim TempTime as Long
 
While Running
    If GetTickCount > TempTime Then
        TempTime = GetTickCount + 10 'This is the speed
        'Some Other Code!
    End If
    DoEvents
Wend

That's the way to go...

In most cases you just want to slow-down the game to say 60 FPS. This would be done like that:

Dim FPS as Long
Dim Temp as Long
 
'Sub Main
FPS = 60
 
While Active 'Main loop
    'Calculate time
    Temp = GetTickCount + (1000 / FPS)
 
    '[Game code here]
    
    'Slowdown
    While Temp > GetTickCount: DoEvents: Wend
Wend

Doesnt that code run the 'game code' too often? or did i just misunderstod the code?

You only want the graphics to update every 60 fps. You want your other game code - input, network, etc. to run while the screen isn't being updated to maximum your CPU cycles.

You probably misunderstood; the loop runs the game code 60 times a second, the other time is spent into the second loop which appears on the last line
