From: ehofman Date: Mon, 30 Jan 2006 13:44:56 +0000 (+0000) Subject: Olaf Flebbe: X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=7e463031951b3abd29841a18c7aca74031cb45ef;p=flightgear.git Olaf Flebbe: I had massive problems with tower.cxx, so I decided to doublecheck all containers and iterators in order and found lot of potential problems. Now I can fly with "debug on" of KSFO for minutes without problems. The fix for AIMgr is from Mathias, but I reworked it. So blame me, not him. --- diff --git a/src/ATC/AIMgr.cxx b/src/ATC/AIMgr.cxx index 022e09487..4fdc5eec2 100644 --- a/src/ATC/AIMgr.cxx +++ b/src/ATC/AIMgr.cxx @@ -213,16 +213,18 @@ void FGAIMgr::update(double dt) { string s = (*apt_itr).first; if(traffic.find(s) != traffic.end()) { //cout << "s = " << s << ", traffic[s].size() = " << traffic[s].size() << '\n'; - if(traffic[s].size()) { + if(!traffic[s].empty()) { apt_itr++; } else { //cout << "Erasing " << (*apt_itr).first << " and traffic" << '\n'; - activated.erase(apt_itr++); + activated.erase(apt_itr); + apt_itr = activated.upper_bound(s); traffic.erase(s); } } else { //cout << "Erasing " << (*apt_itr).first << ' ' << (*apt_itr).second << '\n'; - activated.erase(apt_itr++); + activated.erase(apt_itr); + apt_itr = activated.upper_bound(s); } } else { apt_itr++; diff --git a/src/ATC/tower.cxx b/src/ATC/tower.cxx index 36ca20e75..e2c2e71ae 100644 --- a/src/ATC/tower.cxx +++ b/src/ATC/tower.cxx @@ -311,6 +311,7 @@ void FGTower::Init() { t->planePtr = NULL; t->clearedToTakeOff = true; rwyList.push_back(t); + rwyListItr = rwyList.begin(); departed = false; } else { //cout << "User not on active runway\n"; @@ -528,10 +529,11 @@ void FGTower::Respond() { ClearHoldingPlane(t); t->leg = TAKEOFF_ROLL; rwyList.push_back(t); + rwyListItr = rwyList.begin(); rwyOccupied = true; // WARNING - WE ARE ASSUMING ONLY ONE PLANE REPORTING HOLD AT A TIME BELOW // FIXME TODO - FIX THIS!!!
