Good way to increase running speed?

[megamanw]

So I'm working on a endless running type game and was wandering whether there a way to increase the game speed as the game proceed?? Is increase the character speed a good way or increase the game fps itself??? And how to perform those

I think I can safely say that increasing the fps is definitely NOT a good way to try to achieve this. FPS is likely to vary a great deal according to the capabilities of the hardware your game runs on, so is not by any means something you should expect to remain consistent, or indeed should expect to necessarily have anything like the value you request it to have. I can make a game and tell it to run at 60FPS, but if I then burden it with lots of expensive tasks to run each frame and then test it on a low-end device you can be pretty sure that 60FPS is not what I will end up with!

You can increase the playback rate of the running animation though, and the speed at which the background moves past.

How can I do increase the playback rate???

This will depend on what mechanism you are using to perform the animation and what framework it is built with. You might use a spritesheet based animation and a MovieClip class. My own movieclip class has a 'fps' variable that s used to determine the number of milliseconds that each frame is displayed for. If I increase the fps value this will reduce the number of milliseconds each frame is shown and therefore reduce the overall duration of the animation. Presumably frameworks like Phaser also have an equivalent MovieClip class with an equivalent fps variable.

In addition to what @alex_h said, you could also have a timer that triggers an event such as adding '+1' to the speed you set for the moving objects (the floor/obstacles for example) at a set interval (1 second for example)

 

So if the initial speed is, say 200, then after 12 seconds it would be 212 and so on..
