How is that piece of code being run? Is it being run in a loop? Regards, --Perspx

I've used while loop instead of the top most if statement. The result is same. What to do?

I want to set the speed of the object to 6 if it's travelling between the 1st and 3rd positions. But it's 6 from start to end. How can I set the speed for in between positions(1st to 3rd)? Pls refer to the code above.
Wow, that's a hell of a cryptic question. You have to get out of your code for a while and think that we can't see your screen. For a C++ developper (which lot of us are, obviously, except the ones that get lost on this board), an object is a class. And you can't move a class or make it travel. I guess you are doing something on the screen and displaying something that moves but it is very vague. Now, for incrementing a variable, either you increment it or you don't. You don't have another choice. Maybe you are using a float and would like to have a constant increase of your value when the thing you move on the screen is moving, but then you need to handle it yourself and it really depends a lot on how you are moving those things. When you move such a thing, increment a bit your variable at the same time. That's about all the help we can provide giving your cryptic question.

Which means the
if(pWaypointNum1 < 6)condition will never evaluate to true. Have you stepped through the code to verify this?"Love people and use things, not love things and use people." - Unknown

Your first line inside the while/if statement is:
if((pWaypointNum1 > 1) && (pWaypointNum1 <= 3))
Why not just set
pWaypointNum1to 1 before the while/if statement and then change that line toif(pWaypointNum1 < 4)
as it seems to take integer values? Regards, --Perspx

in the original when pWaypointNuml = 1 testl will be set to 3 your solution when pWaypointNuml = 1 testl will be set to 6
Oh right missed that :doh: Regards, --Perspx

I want to move an Object to a particular point if a condition is met. I use the variable "pWaypointNum1" to refer the position of the object and "mCharacter to refer the Object. Here's the code:
if(pWaypointNum1 < 6)
{
if((pWaypointNum1 > 1) && (pWaypointNum1 <= 3))
{
test1 = 6; //Change the speed of the Object to 6
}
else
{
test1 = 3; //Change the speed of the Object to 3
}
mCharacter1->GoToWaypoint(pWaypointNum1); //To send the Object to "pWaypointNum1"
pWaypointNum1++; //Incrementing the Object's position.
}My problem is: I want to increment the variable pWaypointNum1 by 1 as the Object moves from one position to the next position. But it increments in a sudden. How to increment the pWaypointNum1 variable as the Object moves from one position to the next position?
I hope to understand your problem right. Let's suppose your "Object" is a square, if you want to move it from A to B as "animation" with different speeds... One way to do could be: 1) You calculate the differences in coordinates between A and B. Let's suppose an horizontal line where A is (0, 150) and B (500, 150). So for that example the distance is going to be 500 "pixels" or units of your screen coordinates. 2) You set your different speeds. Let's suppose 10 pixels / sec, 50 pixels / sec and 100 pixels / sec 3)
Speed = distance / time==distance = speed * time==time = distance / speedLet's choose this last one, time depending on the other 2. 4) You make a function to increment in one pixel the coordinate of your squarevoid MoveSquare () { square.x = square.x + 1; }
for such a line you don't need a function, but if you want to do more things or move it in more directions you can ride better with it. 5) When you have to move the square you just need to calculate the time needed with the end_pos and the speed (500 / 10 = 50 sec; 500 / 50 = 10 secs; 500 / 100 = 5 sec) 6) You have to call the MoveSquare 500 times to move it till end_pos, then 1st case -> 50 sec / 500 calls = 0.1 sec / call 2nd case -> 10 sec / 500 calls = 0.05 sec / call 3rd case -> 5 sec / 500 calls = 0.01 sec / call 7) Create a timer with that refresh rates 100, 50, 10 ms and call MoveSquare into it 8) when end_pos is reached, kill the timer Is something like that what you were searching?
