Cocos2d-x learning--android different device fps problems

2014-07-16

Environment: COCOS2DX 2.2.4

AppDelegate.cpp in FPS set to 60

Pdirector->setanimationinterval (1.0/60);

Problem: Run on two Android devices. Two FPS is not the same

i9100:4.0 system, fps approx. 60, (modified FPS is 30, will also change)

s5700:2.3 system, fps approx. 80, (modified FPS is 30, still 80)

This results in the game brush frame, the two machines run at a different speed.

The workaround is as follows (only Android should have this problem)

Modify the Cocos2dxrenderer.java code of COCOS2DX in Android

(PS: If the official comments are modified, it will not be consistent with FPS)

@Overridepublic void Ondrawframe (Final GL10 GL) {/* * FPS controlling algorithm is not accurate, and it'll slow down fps * On some devices. So comment FPS controlling code. *////*final Long nowinnanoseconds = System.nanotime ();//final long interval = nowinnanoseconds- this.mlasttickinnanoseconds;//*///should render a frame when ondrawframe () are called or there is a//"ghost" Cocos2dxrende Rer.nativerender (); final long afterinnanoseconds = System.nanotime (); final long interval = afterinnanoseconds- nowinnanoseconds;///*//fps controllingif (interval < Cocos2dxrenderer.sanimationinterval) {try {//because we render It before, so we should sleep twice time Intervalthread.sleep ((cocos2dxrenderer.sanimationinterval-interval)/Cocos2dxR Enderer. Nanosecondspermicrosecond);} catch (Final Exception e) {}}//this.mlasttickinnanoseconds = nowinnanoseconds;//*/}

Above, thank you
