How to reduce the performance of my game?

Getting Started Newbie Questions
#1

I created a game and the way to get the score is looking the time it took to pass a level.

I have tried a level with my Xperia Pro, and I can pass in 8 seconds

Then I tried it with a Samsung Galaxy and I can pass in 6 seconds, even in the simulator I can also pass  in 6 seconds.

Maybe the character movement is faster in a device than another?

How I can fix it?

Hahaha xD I have never seen anybody wanting to reduce performance :slight_smile:

It’s your implementation how player pass level. If you use movements based on framerate then be sure that this value never will be constant, even on the same device.

#3

Then,  how i can change the framerate? Do you mean fps?

#4

Yes it’s fps. You cannot change it. You can only limit it to 30 or 60 frames per second but real value will be always between 0 and this value.

#5

Hi,

I don’t know what your game is about, but an idea would be to calculate the elapsed time between frames and do calculations with that time, for example when moving a character through the screen you can do

obj.x = obj.x + obj.speed * timeLastFrame

where

obj.speed: Object speed per second

timeLastFrame: elapsed time of the last frame in milliseconds 

So no matter the FPS you will always move at obj.speed per seconds.

Maybe you can work this out for your game
