Is it possible to cap the render frame rate to 50 fps ?

[valueerror]

in the dev branch i found this new feature to cap the physics update rate (desiredFPS)  very useful..  50fps for example are definitely enough for me - 40fps would still do it .. i would have to adjust my game environment a little bit but thats it..   

 

if 40fps is enough for my physics calculations why waste another 20fps on rendering the whole thing? as far as i understand with a framerate of 60fps all my scripting stuff has something around 16ms to do everything..

 

with 30fps it would be 32ms ..  this would definitely avoid lags so im curious..  please correct me if i'm wrong !

 

 

how could i limit the maximum rendered frames in phaser/pixi ?

This might help

thx for the answer but i don't see how this could help..

 

i tried to set every value related to "time" manually but it didn't change anything

 

i don't know if this is even a good idea..  i just hoped to get some info on this..

In pixi to do the same thing I separate the draw + game logic calls and use set time out e.g. setTimeout(Draw, 1000/50); instead of requestanimframe. Not sure if the same thing can be done with phaser.

now this issue became even more important to me..  i am moving some of my objects 10px every frame..

 

 if the gamer has a 100hz display the game would probably run at 100fps ..   and therfore close to twice as fast...  i could bind the movement to a specific time frame but if there was a way to just say to phaser..  "don't you ever render more than 60fps"   it would be nice.  is there a way ???

Don't move them 10px every frame, move them 10px / 16ms.

would you implement you own timer in some way to do this or should i just rely on phasers timer

 

game.time.events.loop(16, moveittenpixels); 

 

?

 

thank you !

i tried it with the game.time.loop   it kinda works but it doesn't look smooth anymore..

You can check in the update() func and keep track of time elapsed..

 

I believe game.time.physicsElapsed is what you need. And then move the correct amount of pixels.

thx ..  i'll have a look at "game.time.physicsElapsed"

i tried this approach..  what do you think ?

 if (game.time.now > timeDelta1) {                   ufer.tilePosition.y += slidespeed;       timeDelta1 = game.time.now + 16;}
