It seems previous use of C# may have gotten me a little bit confused with how I'm attempting my if then statements.

What I am trying is the DarkGDK C++ equivalent of DBPro's

if Upkey() = 1 and walking = 0 then walking = 1

I should really look this up, but I don't have the time to delve into the depths of the internet looking for the solution. (As really I'm just gradually converting my DBP code over to DGDK)

What I did was:



It runs, but the result isn't quite the same as I get in DBP:

I'll do the whole code if it helps:

DBP:


DarkSDK:



What I am doing is making the animation play as the player moves forward and the animation not to plat when its not moving forward. I DBP it works, in DarkGDK the models in stuck on one frame when walking (presumably the last frame) and a different frame when not (The first frame)

You mean like:



?

[edit]

Seems dbUpKey() returns an integer. Maybe better to do dbUpKey() == 1, just incase.

Zotoast, that works better (the values are returned, so that line of the code works fine), but my animation still doesn't play - though in DBP it does. But I'll look into it later myself (Not coding right now)...unless somebody is capable of providing a better version of my code.


In the background when the character is not walking I use these commands, when I remove the first 'if then' below, the 'walking' animation will loop, when I have it, it sticks to a single frame.

if ( dbUpKey () == 0 )
dbLoopObject ( 1, 1, 1 );
if ( dbUpkey () == 0 )
walking = 0;

Sorry if any of this looks slightly sloppy, I've just typed it out into the browser as my laptop connects to the internet here and not my programming PC.

Cheers.

This is a straight conversion of your original code:


If the function names and parameters are wrong, it's because they were wrong in your code

Any non-zero value is 'true' and zero is 'false', ! operates on the true/false value as a NOT, and && is a logical AND (ie, it also operates on true/false values).

That code works too (and looks much tidier, thanks) but it seems more or less that the if, then statements are working fine now as well as the variable 'walking', but the problem is getting the object to animate - it seems obvious that I must have missed something from my original code (I did use instances to do with the downkey as well - though I wouldn't think it would make a difference, but I'll try that when I get back)

For really this is the last I'll look on it tonight, I really don't have much time.

if ( dbUpKey () )
{
if ( walking == 0)
walking = 1;
}

shouldn't it be

if ( dbUpKey ( ) == 1 && walking == 0 )
{
walking = 1;
}

They are actually equivalent. Remember that in C and C++, a non-zero value counts as 'true', and that a nested 'if' is equivalent to a logical AND.
