DarkBASIC Discussion / 2D game sprite speed

Hello everyone!

I'm new to dark basic and I have been working on a 2D game as a project for college. Mainly it's a platformer game where you have to avoid some projectiles.
The problem is that they are just too fast

That would be the code for a lock-on "missile" ball. The problem is that +1 and -1 are just too fast. And using 0.01 doesn't work. Is there a way to make it slower? I really don't want to come up with a game that requires skill equal to dodging a bullet in real life.
Please help me if you can.
Thanks in anticipation!

Hello robertpas! Welcome to the forums!

You had the solution right to use numbers that are less than 1. Here is how to make them work:

The trick is positioning the sprite using float variables, rather than integer values. The sprite will still be positioned at the same place, but after several loops through, it will increase by 1. When positioned, the command will drop the fraction.

Hope this helps!

BN2 is quite correct. Also note he is using sync to update the screen. You can declare a float using # on the end of the variable name, or defining it at the start of the program as a float. Also note that sync rate 0 will run at the fastest speed possible, rather than a steady 60 fps for instance. You may want to use the timer() command to get it running at the desired frame rate, which affects your game speed also. You could of course set it to 60 instead of 0, but that will actually introduce pauses in your game and is best avoided.
