3.5 AOI格子添加删除操作

mmo_game/core/aoi.go

//通过GID获取当前格子的全部playerID
func (m *AOIManager) GetPidsByGid(gID int) (playerIDs []int) {
    playerIDs = m.grids[gID].GetPlyerIDs()
    return
}

//移除一个格子中的PlayerID
func (m *AOIManager) RemovePidFromGrid(pID, gID int) {
    m.grids[gID].Remove(pID)
}

//添加一个PlayerID到一个格子中
func (m *AOIManager) AddPidToGrid(pID, gID int) {
    m.grids[gID].Add(pID)
}

//通过横纵坐标添加一个Player到一个格子中
func (m *AOIManager) AddToGridByPos(pID int, x, y float32) {
    gID := m.GetGidByPos(x, y)
    grid := m.grids[gID]
    grid.Add(pID)
}

//通过横纵坐标把一个Player从对应的格子中删除
func (m *AOIManager) RemoveFromGridByPos(pID int, x, y float32) {
    gID := m.GetGidByPos(x, y)
    grid := m.grids[gID]
    grid.Remove(pID)
