Sprites with different speeds

[crazzter]

First of all: I'm really new to this stuff so please bare with me  (I'm mostly a backend guy with an urge to gain new skills)

 

How would you go about making one sprite move ten times as fast as another? I'm saying "ten times" and not "twice as fast" on purpose. Twice as fast could probably be accomplished by doing this in the animation loop: 
   sprite1.x += 1;

   sprite2.x += 2; 

 

But jumping 10px would not look very nice :-) Most of all it's about learning to do things right. Not just making it work.

 

Hope my question is not too trivial or stupid 

 

TIA!

Don't take this as saying your question is stupid, but... think about it for a minute.

If sprite1 is moving at 1px per frame, how can sprite2 move at 10 times that speed without therefore moving at 10px per frame?

So the example you proposed for moving at double the speed is also correct for moving at 10 times the speed if simply changed to

sprite1.x += 1;sprite2.x += 10;

Whether or not moving at 10px per second looks nice depends on factors like frame rate, monitor refresh settings etc.

If you are interested in making movement look nice then I recommend reading up on animation with tweens, easing algorithms and so on.

Thanks a lot! I had a feeling it would be the only solution but was afraid I was missing something 

Well, at least I was getting it right in the first place! I'll jump straight into the reading-material!
